If I had to guess it's either one of three things -> 1.) Plants being too close to the lights, especially if you're using HPS. 2.) Your PH. 3.) Your P04

I would switch them now if they are 3 - 4 feet, they may well reach your 8 feet ceiling, mine did.

Top leaves curling usually is a sign of extreme heat stress, how close are those 1k laser beams

PICS!!! Not able to help w/o pics. It SOUNDS like it could either be a nute deficiency or lock out (whats your pH?), or a Cal/Mag deficiency. We need good pics to say with any degree of certainty. Not phone pics unless you just don't have anything else. Try and get them in focus. If you are under HPS, turn them off for the pics.

You can get a good digital camera at a pawn shop dirt cheap. If you're gonna grow, you really need a good digital camera. You don't need 20 mega-pixels, 5 to 8 will do just fine.
