Can someone tell what caused this abnormal condition to leaves?
Before that I flushed her and supercropped main stem and fed 420ppm 5.8ph under 600w hps(10days in). 55-60RH 28C
Hey there.
Are you in coco coir? Looks a little over fed with nitrogen..
Are you getting 10-20% percent runoff when feeding? 420ppm seems low, not getting runoff will stack your nutrients which would explain high N when feeding low amounts.
