Wilting green plants.....HELP

[Bishop420]

I had a plant wilt....it was still green so I thought I was having deficiency problems. The rest of them dont look so hot either. So in disgust I left lights off and fan on almost 24hours. Woke up this mourning and she came back. Im using cfl's and humidity levels are at 43% when I leave the door open. WTF????????
I know for a fact I have deficiency problems because I didn't know I have to use some sort of nutrients.
I also recently pulled a flat of them out of the closet for this same reason thinking they were going to die.....they haven't been under light in 2 days. Just sitting off to the side and those look healthy as heck!This is the before pic.....Im loading the today pics in a few. The pic with 2 in it...its the one the right that was wilted badly

you don't have any kind of meter to test the drain off? because looks loke either way way bad toxic build up or your temp's are freezing cold those are the only times i've seen plant's like that, what about the media? fell it and see if it's too cold if it is it's probably locking out certain nutes while going toxic on others, leaving the light's off is usually always bad, what you need is a complete hydroponic nutrient formula or complete organic formula that 1 that's totally wilted is damn close to dead if you don't get a complete soon and flush all the plant's at least 4-5 times befor adding it a 1/4 strength there all gonna die, hope this help's N

dont really understand some of what you said. Dont see how temps could be to cold but I will take ur advice on that. How do I test the drain off? I have a soil tester from wal-mart. It has these little pill capsules in tubes. Not sure how to use it. I have to go get nutrients but cant do that till I get some money this week end. It is my first grow and first room. Alot is wrong. I have a friend whom Im hoping to treat to a nice steak dinner and hopefully he will help me fix my hack job of a room. lol Thanks tho, and I really appreciate ur time....Bishop

bro don't listen to NOTB he doesn't kno what he's talking about. the lights would raise the temps, so why would they get better with the lights off... it dont make sense... thats def. not the problem. Anything below 50 F plants wont grow, but will survive untill it gets below freezing. If its indoors i highly doubt temps are it. Im not an expert on this shit but a geuss would be a case of overwatering. Also pretty sure some Nitrogen deficiency as well.

you should really post the other 6 pics of your plants you uploaded 20 min after those 2. It'll def. allow people to be of more help. Unless u think u got this prob figured out. but trust me hommie dont think ur plants are cured jus cuz u left em in the dark for 2 days.. if they are that'd b a f in act of god. Get some nutes stat bro and figure ur moisture out... im personally not sure what one... prolly a bit of both. Hope i helped out a bit, stay high

Add some nitrogen and watch your watering frequency, make sure the pots are nice and light when you water. Nitrogen for sure though Have good drainage in those pots?
