Mostly senescence... maybe a slight imbalance in feed. The red and purple are fall colors -- either genetics or temps hare going below 68F at night and the chemistry in plant results in these colors due to temperatures. the burnt spots.. that's some sort of imbalance. lockout - ph or nute-lockout - typically causes numerous and confusing symptoms that won't lead you to 1 answer. This seems liek senescence and possibly a minor nute issue occuring. This seems wy too early to be turnign fall colors, so i'd wager it's the temperatures during dark cycle. would need more info to help figur out possibilities of anything related to nutes.
