Hey C of Green, I hope things are going good for you. The rusty spots and leaf curling that you see on a plant, is it only on the AI? When I grew my AI, I had the same problem but things turned out fine at the end of my grow but I didn't know what was causing it. It could be that you are feeding it to much though. How often are you feeding them nute? Keep Em Green man :thumbsup: ...
