Help- just changed lighting

Hey guys, i have four plants that are about 2 weeks into flowering, i just moved them from a room with CFL lighting to a new room with a 400w HPS system. They are just about finishing their first 12 hours in the new lighting and they seemed to be shriveling up and drooping. Up until this point they seemed pretty strong and blooming. I was wondering if this is normal under these new conditions for them to change like this. I have also just watered them as well.

How much do you water? Is the light 2 close? Any Pics?

I watered just until you could see water leaking out the bottom of the pots, just as much as I usually do- it's usually fine. I put the HPS pretty high so that they could have time to adapt, they aren't touching it or anything.

Is it to hot? Or maybe nutes, what are you feeding them?

If your temps are cool, lower your HPS and add a veg cfl or two.

Don't assume you're plant is getting as much light from an HPS two or three feet above versus a cfl an inch away. You may changed it so they get less light.

Other than that it's kind of normal for the plant take a couple of days to adapt to the change from using the blue lights to having none.

The temperature isn't a problem, if anything it's too hot. I'm guessing the extra heat caused them to dry up. Any ideas on how to reduce the temperature?
