Hello,

 

 

My plants showed yellowing tips around two weeks ago. I made a post here and was told it was nutrient burn. Now i'm thinking it might definitely be a deficiency. Uploaded are a few pictures, including the fert i am using. I water once every 3 days. around a Litre per plant. every other watering i do a feeding. How i feed is i water the plant normally, then after 15 minutes i make a tea of 1 Litre mixed with 1/5 of a teaspoon (12-12-17). I water using tap water. and I have been kind of changing up PH every now and then, but i don't think it is a problem as the soil always buffers it down to 6-6.5.

 

Oh and btw can you check the pic of the fert i am using, as I did not see Calcium written on there!?

 

Age: 45 days, day 3 in Flowering

Pot: 3 Gallon

Soil: Universal Potting Compost (A bit of clay in it) (also has 0.75kg of NPK per square meter)

 

Can you please spot any problems or deficiencies?

 

 

 

 

 

 

 

 

Notice the purpling stem? it is only happening to one plant though!

 

 

 

 

 

Next up is the damage on the leaves.(Almost only on Fan leaves?) (Also new fan leaves start out with white tips) (Also a bit of dark stripes in the leaves)

 

 

 

 

 

 

 

One last thing, I spotted a few(3) white flies, they were tiny. I made a solution of soap and oil in a spray, they seem to have disappeared.

 

I am thinking Calcium deficiency? Then again i am a first time grower.

 

Thank You for your replies <3

i don't think the nutrients you're using are complete or well balanced for cannabis. if your meter is accurate a soil ph of 6 is low.

 

edit: meant to say are not complete or well balanced

I believe you have a potassium issue and maybe a calmag aspect aswell. Not sure why though. So we have to figure this out before trying to fix it.

 

First:

Stop feeding at different PH ranges unless you have reason. I believe you said you do that but dont care because of soil buffers. Do not do that. You might show a bit of it in one of your leaves but I think its something else maybe. You should think balance and work towards that direction always. Any changes should be due to plant growth period needs or other aspects/issues.

 

Second:

I dont understand your feeding. Are you saying that you give them water, then wait 15 minutes and then water in some nutrients? If that is correct, explain why you do this.

 

Third: Explain when you started feeding the plant initially, when issues showed and all that you did. Also, if you changed your process during the way. Such as if I have correct in how you feed if you fed differently I want to know when in the timeline of events did ths take place.

 

I suspect you have mismanaged your soil and your roots are not happy. You are making a simple thing complicated so it is not easy to ascertain accurately your issue. Due to this, I would repot in new good soil and feed and water correctly in a way that promotes balance.

 

I recommend go and reading the basics of growing, search terms like cannabis grow bible or nutritional needs for cannabis or what have you. Understand what the roots are doing and what the plants want nutritionally and why during its development. Do this and you will be better.

 

This is the second time I said this to you about reading about the basics aspects of it. I guess you were not serious. Best of luck to you!

Yes that's correct. As i said, this problem has been happening for two weeks, and I was very worried. I felt I didn't have enough time to try new tricks or adjustments to the plant to cure it. So I just concentrated the fert into less water so the plant could absorb it more intensly, in this way I would get a reaction from the plant more quickly so i can do further research towards my problem. I am not a botanist or a pro, this is my first grow, it is just something i FELT would work. :)

 

I thought of it as a quick injection to see if it would like it or not, rather than change over time.

 

And if it is Calcium def. What do you think about egg shells?

 

​Oh and btw I started my first fertiliser feed on its' fourth week alive. I made an EXTREMELY hot mix. Yellowing leaf edges occurred. I got scared and stopped fertilising it. I then transplanted them from 1gal pots to 3gal pots with new soil mixed with around %30 perlite. The reason I am worried is that where I live (Hint:Dessert). It is VERY difficult to find a trustable fertiliser brand. The picture below is the only fertiliser i found. And I flushed the plants around 2 weeks ago, shouldn't that have fixed my issue? Perhaps the plant was nute locked from three weeks ago and hasn't recovered?

 

Respect for the answers you gave <3

 

One extra note: My roots have been growing crazy fast btw. When i transplanted, I noticed that the plant FILLED the whole 1gal pot with roots in only 3-4 weeks. Tomorrow i will check the root ball and send pictures, but i can already see tiny roots sticking out of the 3gal pot. plant is 45 days old.

egg shells are great to add when making a soil mix that gets a good 8 week cook. powdered oyster shell may be a little faster.

 

if you can order off amazon i'd suggest getting an organic tea mix. bu's bru is one brand that i know is good.

Um, dude, those plants look pretty darn good, just sayin. Ditto on the over complicated, real soil growers never test PH, a good mix will self correct. There are just too many things going on in soil processes to " manage" ph, and, that's almost NEVER your problem in soil.

 

A few of those spots look like light or heat burn, but they are older leaves, I get a bit most grows. I agree on the repot in a good soil or rather soilless mix, forget ph, and just water it, they'll be fine.

 

Most issues are caused doing too much, not too little. Peace.

Im %100 sure it is not light Burn or heat stress. I will wait a few days until the soil dries out then will replant it into perhaps a 5 gallon pot. But IS IT OKAY to transplant in flowering? it is 4 days into flowering.

these are clones, the damage is on the leaves that were on the cultivar when you cut it to clone, THIS IS PERFECTLY NORMAL!!!!

 

K equals Calcium. the K stands for K2O (Gypsum).

 

Purple stems are most often genetic.

 

If you don't quit obsessing over your plants your going to wind up killing them.

BalzaSteel Once again, These are not Clones, I germinated the seeds myself. The strain is HAZE X. And ya I guess i will just leave them alone, as perhaps I have been over caring towards them.

Green Jesus, brother you have to stop with the "hot" mixes... youre gonna end up killing your plants. First time growers should spend some quality time reading about how this plant is grown and pick the right method for you.

Asking questions only gets you so far, if you don't already have the basics down. You're looking to grow as simply as possible, it doesn't take a lot to grow some decent plants all the way to harvest.

 

If you want to add egg shells to your soil, that's ok, but it's going to take quite a while for them to break down enough for the plant to be able to utilize them. Adding liquid cal/mag to your feeding schedule will work much more quickly, if you need those nutes now.

 

I would go along with the suggestion of repotting into new soil. With all the issues you've been experiencing, new soil may be a much better idea at this stage than flushing the soil the plant is sitting in now.

 

If you choose to repot, I would suggest that you leave the "hot" mixes alone and aquire a balanced nutrient solution and follow the directions on the label. Remember, a little less is most often better than a little more when it comes to feeding your plants.

 

I've seen a lot of first time growers make these mistakes and worse, but growing plants and harvesting those plants can be accomplished once you get the basics down and start actively learning how to grow this beautiful plant we ALL love so much!!

 

Good luck and if you need more assistance, we'll be right here.

 

Keep it green!

sorry m8, got you mixed up with another grower, also K is potassium not calcium, doh :)

 

I think the wisest course for you would be to invest in a cannabis specific nutrient and follow the directions starting at 1/4 strength and work up.

 

the fertilizer you're using is for acid sensitive plants which cannabis isn't, it likes slightly acid soil.

 

I'd go with earth juice, but just about any canna-nutrient would be 10 times better than what you have. Heck, miracle grow or peters would be better.

Just get the grow and bloom formulas, forget about the extras until you get those figured out.

 

If you bake eggshells at 250 degrees for 1/2 hour and pulverize them in a blender they'll start to break down in days instead of months/years.

 

your CFls could/should be closer to your plants, as a rule of thumb if you put your hand just above the plant between it and the light and it feels uncomfortably warm the lights are too close.

 

I use CFls and have learned that they need to be close to get enough light, I pick off any leaves that stick out towards the light so I can get the plant as close as possible without burning leaves.

Reflectors would be a good idea, foil pie plates and foil stove burner liners work ok and are quick and cheap.

PS: I've found that asking google works better than asking on a forum, takes longer to get the info, but I usually end up finding the answers to half a dozen questions I haven't learned enough to ask yet.

Alright thanks Balza, and I kept the cfls a bit farther to induce stretching, since it is way too bushy and leaves are getting packed. Where i live there is no nutrients that are known or trustable, AND IT IS IMPOSSIBLE TO FIND cannabis specialised stuff. I guess i won't feed it anymore, as the nutes in the soil should sustain the plants. I will give it a few days and if the problem keeps getting worse, then i will repot, thats all. :)

 

And really thanks for all your replies Balza and everyone else, I really appreciate it. <3

try ordering on-line, shipping will be a bit high, worth it as the bud tends to burn cleaner.

 

any nursery and most garden centres carry a good selection of fertilizers, a general purpose high Nitrogen for grow and a high phosphorus for flowering/fruiting plants will work, just make sure they're not designed for a certain type of plant or condition.

They'd also have quality organic nutrients/ supplements, guano, kelp meal, green sand, glacial rock dust ect.

organic nutrients can be harder to use, they don't break down as fast so you have to be able to see what's coming and you can't just flush them out if you screw up like water soluble fertilizers.

 

don't worry about not enough stretch now, worry about too much stretch after you flip them.

 

CFls need to be close to provide enough light for the plant to flower well, if your plant stretches more than a few inches you'll end up with a few short buds on the top and popcorn on the rest of the plant, a wide bushy plant with lots of colas stretches less and lets you keep more plant closer to the lights.

UPDATE:

I have been using normal tap water for the past two weeks to see if the plant would get better.....Well, it didn't. The yellowing and Burned(Brown) parts of the fan leaves have been getting worse and VERY quickly too... A few bottom leaves fell from each plant. The leaves become Extremely Yellow and the brown areas become spread from the tip of the plant all the way to the end, then it dies off.

I'm thinking of maybe getting Epsom salts from a pharmacy or something. I do not think it is Nitrogen deficiency as I mixed 1/10 parts of Urine into a watering session. I know that a nitrogen deficiency won't be resolved just two days after I use urine, but the shrivelling and dying of the leaves should at least STOP, well it didn't. What do you guys think? what type of deficiency could it be? and its nothing with roots, as I took out the rootball of the smallest weakest plant and it seems the rootball is perfectly fine, not soggy, not brown, and does not have pests.

You gotta research what each nutrient deficiency does to your plants. There are mobile and immobile elements, with deficiencies showing in old growth and new growth respectively. Some are slightly mobile and deficiencies will show up generally throughout the whole plant.

 

Then you need to look up what toxicities will do to your plant. Too much of one thing will lock out another, and your plant shows a deficiency that doesn't exist, and needs to be backtracked. This happened with someone in Mapito recently, and I believe spacecake mentioned a too-high EC as the cause, and sure enough a little extra water in the res solved everything.

 

 

P.S. Epsom salts are almost never needed in soil.

@ gj your plants are ok the bottom leaves are yellowing as they are not getting light to them down there the tops look nice i dont no to much about soil as i grow in mapito so i am just going from what i can see in the picks if you had a calmag prob it would start at the top not the bottom when leaves strat to yellow lower down its one of 3 things lack of light over watering or lack of food so to me it looks like not enouth light the leaves that are looking dead and shity you can pull them of as the plant dose not need them now it will not hert them .now this is what i would do

1 all ways water from the bottom A 1/4 way up the pots let this sit for 10/15 mins so they can suck what they want up

2 get a p.h pen so you no for sure what the p.h of the water is as adding nutes will lower the p.h i have all ways watered my mums @ p.h 6.2 they love me big time

3 if you flush the soil ALL WAY FLUSH WITH SOME MUTES IN NEVER WITH JUST TAP WATER or you will be going from one prob to another prob A lack of nutes.

 

so now just water your girls and add what ever you are feeding them but just add a bit les the plants will tell you what they need

 

now all the soil lads will jump on me but thats just how i would do thing and they fuck about with soil more then i do

looks like a slow progression over last two weeks. collar and over all health look good. problems with a few leaves shows that not everything is perfect, but your not missing the mark by much. i think you're likely shy of more than one element in the soil but should be cautious not to over correct.

have you done anything to add any cal? balls' suggested using gypsum, got a piece of dry wall available? strip the paper off and grind up a tablespoons worth to add to watering or top dress with.

I did some research....what REALLY looks like my deficiency is Potassium...burns that look like nute burn....curling upwards....yellowing and shrivelling up....weak stems and red petioles....exactly what i have....i guess i could flush the soil today and use the fertilizer i currently have... 12-12-17 since the 17 represents potassium i guess it is a good match...and they say calcium could inhibit potassium absorbtion so i wont take any risks with that....also they say heavily filtered water could be bad for potassium use, and i have been using mineral water for like the past 2 months so maybe that is why....

 

Thoughts?

Thanks <3

I stand by my original post. I see nothing of change. Stop guessing at stuff and get to knowing it. This is pretty much my statement to new growers:

 

Some things to understand, search for things like cannabis bible and such:

 

Plant nutrition - know what it wants and when it wants and how best to give it to it. Learn about foliar feeding, top feeding and bottom feeding, brix levels and about different fertilizer types (organic, bio-organic, soil, soiless, hydro, passive hydo etc.)

 

PH - Learn what PH does, how to raise PH up and down, PH in soil, hydro and soiless medias, and learn how PH and plant nutrition work and what nutrition needs to be at what PH to be used. Learn about PH lockouts.

 

Plant management techniques - Learn about the different ways to control and manage a plant. Learn about cloning & mothers, learn about seed growing and differences between seed and clone. Learn about LST (low stress training), super cropping, bending & pinching, topping, fimming, leaf trimming.

 

Harvesting & Curing - This is a tough one due to so many view points. Use peoples advice when to cut who view the plant in potentcy similar to you. For what it is worth, what most people call ready to cut here, I would say needs almost several weeks to go. This area is very subjective. Learn about the properties if the trichromes and decide for yourself when best to cut using other view points as a guide. If you truly care about top flavor. Then learn much about curing.

 

Pest & Problems - Read, read, then read some more on this. You will see problems. Most common are calcium and magnesium based and pests. I am all about prevention. Think of it like having sex with a loose woman. You might want to wrap that up. Same thing with prevention. Their are alot of swing dicks in the pest community who want to visit your love shack. Learn about organic controls and pesticide aspects. I personally like organic and cannot speak enough on predator bugs. I like nematodes in the soil and if you have any flying pests than getting predators for above ground like assassin bugs or even the very pretty lady bug and things should be well.

 

Anyways, understand about prevention and how to handle an infection. Most people do not do prevention so they get infected then they are about prevention. To go into this category is to accept that you will have a diminished crop. Do not pay that price to get serious about pest management.

 

Learning the signs of nutritional and stess aspects will do much for you. Learn about the heat stress, over watering, underwatering, Calcium issues, magnesium issues, nitrogen issues, phospherous issues, potassium issues and PH issues.

 

When anyone says, "you dont need to do that" keep in mind, they are likely more experienced and knowledged than you. Until you develop to where you feel you do not need to do or test something. Just think those words are cute and thank them and "you" be competent in what you do.

 

I also will add, stop pissing in your plants. I know you are using very little but do not do this. In fact, who ever told you to do that, do not listen to them. Perhaps if you used the piss from a natural human perhaps but you are more plastic and chemical than you are natural thanks to our modern lifestyles. This comes out in your piss and you put into your plants. Any medications, poor diet and such. Your piss is also no consistent. You have no appreciation for what you are doing on many levels levels. While it is good to be bold at times, being bold without understanding without reasoning is foolish.

 

Good luck to you. I hope to see a happier grow but you will have need to get dedicated to doing things correct and actually doing some reading and learning if you wish to grow well. You issue is not so bad if you fix correctly.

 

I also would repot your plant into a good soil and manage it more proper from here on out. From all that you did, you have messed it up. It will grow a plant but will not an equal if you change the soil.

Actually their are many uses for human urine but in modern times we obtain the raw materials used via other sources and human urine now is a waste product. It was not always so. The history of humans piss is pretty neat actually.

 

The article is about make something else from urine and not using urine direct. This is problematic as the diet of people today are different and more unnatural than natural. Urea is in many fertilizers but this animal based urea is more standardized. You can buy the base materials and just make your own fertilizer inexpensively or use directly . Get the granuals if you do. Think of Urea as a nitrogen punch!

 

Notice they talk about in the article about vegans and such as these people will tend to live a more natural food intake lifestyle than the typical westerner. The quality of their piss is potentially more natural and stable. So in this group this aspect might be cleaner. Think antibiotics, medications, processed food ingredients, eccess minerals - do you take vitamins and such, and whatnot just to start of some aspect of unnatural piss and one aspect why this is not a good source of material to use.

 

I would tip my hat to someone who is really really wants to make their own nutrients from their piss as the work will take far more effort than it would be do buy it or even just to make a worm castings or bokashi.

 

I have seen a lot in this world from grow styles. I actually travel, meet, learn and work to obtain what I act like I know. I am very well versed but a master of none. I have never seen people do this for in part some of the reasons I have posted. (I am talking about making nutrients from their own piss) It is common for people to use standardized urea on crops bought in granuals but they are typically professionals in the growing industry with much understanding and knowledge.

 

While I am sure their are people who do it, if they have a system and it works for them great, but their situation is likely quite a bit different than the typical reader and thus the results will likely be majorily different. Generally what you will see is the end result of that persons learning curve and this is not realistic towards newer unexeperienced people or you see a farmer do it and think, hey, I can do that.

 

Before you try, learn about the aspect in depth or people will likely burn/hurt their plants.

 

Think of urea as a base nitrogen product, not human urine.

hahaha i forgot about this thread, well damn Hempy you wrote a whole lot about piss XD......Anyways:

UPDATE:

Week three of flowering, plants look great. I flushed the hell out of my soil, then made a strong tea of the fertiliser i had before(12-12-17). Used the ferts on my plants, I got a little nute burn but it was necessary, as the deficiency has stopped!!! :) Lower leaves stopped dying out, stopped getting yellow and crispy, and the plant is producing buds quickly...... I will use a mild fertiliser tea next week to lessen the nute burn.....Getting pics for ya soon enough!
