Looking very healthy. Some are a bit on the yellow side like you might have noticed too. But besides not being it my favorite color on the leaves of beautiful plants, certainly not with reds stems and unfortunately they tend to go hand in hand, experience taught me - and may i add that experience is my favorite teacher on earth - it is really not a biggy. Not at all. Some even say that yellow plants deliver the best.
Different plants require different foods and i know you all know all of this and this is what happens when experienced growers cross paths. There ain't much to say besides that there ain't that much to say and sad as it may be i said it!
Nice first clone only grow, no turning back to seed if you ask me! Have a nice day @Misterdirt
