Are My Plants Overheating?

Here's the deal. I'm growing 4 pre 98 bubba plants in soil in a closet. They're almost done with flowering and the tops are starting to get crispy. I'm worried because if it is the heat that's doing this to them, there's nothing I can do. Their day cycle goes from 9pm-9am so the lights are off during the hottest part of the day. If they're getting burned it's at "night" and other than moving them from my oven-like closet grow room, I don't know what I can do. I moved them to the floor of the closet just to cut down on a little bit of the heat but I'm not sure how much that's going to help. Last night when I saw this, I switched them to distilled h2o. No nutrients. If I have to harvest sooner than I planned, I want to make sure they're flushed.
Like I said, they're almost done flowering. Will they come back from this within a couple weeks and still be good or should I cut my losses and harvest now before it gets worse?

Hey guys. Sorry if bumping a thread is a no no but I'm really concerned about my ladies and I could use some advice.
Thanks

move a fan so it's pointing at your light, not your weed. then make sure that you can comfortably keep your hand under your lamp without feeling like you'd get sunburn from it (if your plant is closer than this it will burn). using cfl's ? try and use reflector's rather than placing the plant so close to the light.
ur bud may not be ready, test a lil bud and see if it's satisfactory then put it in a dark room for 3 day's before harvest (i've heard it's good to boost thc).

Thanks for the response! I'm using CFLs and the bud's are about 1" away at their closest. I really don't think that's the issue though. They're getting damaged during their night cycle (while lights are off) and I've got one fan on the lamps and one oscillating on the plants. The lights go on at 9pm and off at 9am so that during the hottest part of the afternoon, I'm not adding to the problem with my lights. The problem is that I live in a hot area and since it's gotten worse in the past week or so, my plants are still frying during the heat of the day.
I did cut down a small piece a few days ago and I've since sampled it and it seems pretty decent for not being cured properly. The tops could use a little more time but they're probably ok to harvest right now. The lower parts of the plants definitely still need a week or two. I'd hate to have to harvest too early and then end up with a mostly shitty crop to show for all my hard work.
What do you guys think about cutting down the tops and leaving the bottom area of the plants to do their thing for another couple weeks? How about tips for getting it a little cooler in my grow room? I've been doing as much co2 as I can afford. I'm misting them with sparkling water and I've got some yeast bubbling in sugar water.
Thanks a bunch

Could be to much nitrogen in the soil, I'm having a similar problem but my girl still in vege stage.

Its too hot and you need better soil and feeding. How hot is it?

ohhh shit, ouch!! My first thought was that is going to be some harsh ass smoke, but I see they been fried like an egg. It looks like over fert 10X, but if its only the heat then freeze some gallon jugs and place them by your plants, might help bring the temp down a few degrees. Ice cubes around the stalk will also keep the roots cool and not cook them.

I would give them a super flush 1.5 weeks before you plan on cutting them. I would flush like ten times the size of the pot. so a 1 gallon pot would get 10 gallons of plain 6.5 water, it will make the smoke way smoother and taste better. (normally 3-5X the pot size would do but you have severe case there!!)
