I'd also switch to tap water fro the Calcium in it. The leaves that are already dead look to me like they had been Ca deficient, among other things.
You are ready to start feeding.
I see what looks like a potassium deficiency too, but it could be scarring from previous insect damage. Looks more like K def though. The brown spots. Plus N def- the splotchy paleness around them.
A feeding with fish emulsion should take care of both the N def and the Ca problem btw.
stinkyattic Reviewed by stinkyattic on . What is going on here??? One of my youngsters has some strange stuff going on with the leaves. After reading about lockout and roootbound, i will be transplanting today, howver I don't think that is the problem. Can anyone shed some light for me? They are 5 weeks old, MG potting soil, RO water only no nutes, 18/6 germed from seed. And while we are at it, can I set to 12/12 now to sex and then return to 18/6 without too much stress? Thanks.
