@Need4Weed this week, I dunno what week it is. Auto GSC.
Any advice will be well received. I have the pH bang on 5.8, 200 watt COB's are at 25-30 inches, RH is 55, Temp is 70F. 500-600 PPM Green Planet Hydro Fuel, with Root Builder and calmag+... Good airflow, Roots are clean, but not super developed, old leaves are drying up, new leaves are good.
This is the second grow with these lights, and the second time I've had this problem. I grew right through it last time and got a good harvest, but I'm not as confident this time. I keep thinking this is a lighting problem, because environment is solid, and I never had this problem before. It can't be deficiency, or lockout. Not sure what to change.
