need some "H E L P"

we just moved 24plants from our tent (veg room), to our flower room. we had '1' 1000w light on for 3days, thereafter we added an add. 1000watter..

they are in waterfarm, and we always start off with little to no nutes for a week/10days..

here is a pic of the plants... any ideas what may be wrong??

someone said maybe heat, tho the temp is 80F, with fans ... I'm stump'd
