If diary accurate then you are feeding way too much at 2500ppm. If soil your ph needs to be higher. Most plants prefer a rest period. However some swear by that 24 hour thing. I can't think of anywhere on earth a plant gets that much sun.

What is this brown intrusion upon my plant? And how do I obliterate it?
Another question?! Anyway, what the hell is this browning? I think it's light burn. But why is it lower too? PH? Magnesium? Nitrogen toxicity? Par: 1300 PPFD Fox Farm tiger bloom 7 ml/gal. Fish Shit 3 ml/gal. See diary for environmental conditions. Thanks for the help. Again.
