it looks like you got some water or nutes on there and the lights burned them.

your temps are getting pretty high. are they in a box or tent and if so what size? are your intake and exhaust fan the same CFM?

and your res temp seems to be getting a little high. i'm not a 'dro guy though, so don't listen to me there. i'm sure one wil chime in.

did you soak your rockwool in pH'd water?
