thanks for the replies guys. I think it was damage from the light. cuz I mean at one point before I was able to move my light up it was about 2 or 3 inches away from my plants and that's a 600 watt bulb. could the burns look like that though? I think I will just give them ferts tomorrow for the first time at one third the dosage and see what happens. I only give them that once a week though right?
