does this look like nitrogen burn

high i was wondering if this looks like too much nitrogen or what your thoughts were. thanks for your help.

the edges of the leaves are starting to curl up, in an almost crispy looking sense. not that they are crispy just what comes to mind when i look at it.

Nope. Slight heat stress.

I was recently having that problem, and it was a combo of 'low PH' and heat stress. I didn't think it was the heat, because I always grow plants with the lights that close, and never had a problem. But, with the PH being way low, it stressed the plant and made it less resistant to the heat, causing it to suffer from heat stress in an otherwise normal situation.

Just a possibility.

awesome thanks for the help guys. it's been getting pretty warm lately so that makes alot of sense.
