Why is One growing perfect the other is struggling
Why is one of them doing so well growing better deep green leaves and the other is at least 2 inch shorter and leaves are yellowish. I’ve been feeding them both the same I’ve missed the shoter one of the soil is still damp. I’m guessing nutrient over load so thinking do a flush

Yellow leaves at bottom. New growth good. How she looking?
Tried a new nutrient line, instant Pythian(sp?). Switched back now and she seems better. Should I be concerned at this point? New growth looks good to me. Although she seems droopy for this time of day. My theory is that the new line was more sensitive to warmer water temps.

Seedling yellow leaf ?
A pair of second set leaves have sign of yellowness (it occurred a day before transplanting). I'm not sure whether it is Nitrogen deficiency or any root problems? (I will start adding more Veg nutrition which is rich in N this week) Can yellow leaves turn back into green?

Hi everyone.. The leaves that are turning yellow, could it be due to over-fertilization? Or excess nitrogen?
