PLant Burn??

Im flowering right now, have a 600w hps, It was about 7inches from the top of te plant today when I moved it up a little more, I might be burning it, Im not sure the edges are not yellowing but the leaves seam to begetting faded by the intense light. I dont have any close up shots, becasue its the dark period but If anyone could tell me if from that description waht tehy think. I was told if my hand doesnt burn the plants wont but I feel like I can put my hand like 3inches away??
Any info or thoughts,

the pics arent good for what Im asking but you can kind of tell the light distance

They look like they're gettin hot, see the leaves curlin down away from the heat? Try aimin a fan at the light or Raise ur light to a save height when it come on next, start it out like a foot from the tops of the plants. Scrap the 'heat on the hand trick' and get ur thermometer and get actual temp readings. I got mine rigged on a string that I can raise and lower as i please, I keep it right around the top of the nugs so I know theyre good.

yea thanks man, I held a therm under it for a lil while and under the lights was damn near 95f, my room is a constant 75f, Ill move the light up tomorrow, thanks man, also does there seem to be any lasting damaga or if I take care of it now will I be ok. thanks again

There doesn't look in the pics like they got it bad, so the damge should be minimal. U'll be fine as long as u keep em from burnin up ya know? Seriously, that's not bad, I've seen guys totally crisp up huge nugs from the heat I MEAN CRISP! Find ur right height with that thermometer and u should be gettin some nice nugs soon!
