Plant problems need diagnosis

Alright well having a a few plant problems I belive I am having 2 issues one with nutrients and maybe heat stress? I have since moved to a diffrent light. I have yello/white spots red leaf stems and the fan leaves curling up-- any help?

I have similar problem without the leaf curling after changing from fls to 400w hps.Not had any replies,so i am still in limbo.
Good luck with the grow.

what is ur heat level at? that looks like some nitrogen or phosphorous deficiency. have you checked your ph levels?
