A few of them look like they might have some nute burn. It's possible they got nutrient lock. Are they hydro, if so, do you have enough air getting to the root (an air stone or something). If not, that might also cause it.
Also, check this site out for tips.

Is that steam? The ideal water temperature for hydro is 65F (it holds the most oxygen in it at that temp). What's the reservoir temp?

Points back to nutes again. All I can recommend is straight water or very very low ppm for a couple days, and hopefully they turn around.

wow i've never seen things go so wrong so quickly, but fixable. My first thought is root rot, this is prolly what caused what i thought was magnesium def. Root rot looks like a brown goo on the roots, and will always lock out some elements or nutrients or water or anything. Thats what i see on the bottom of your cups. It can also be a bacteria, i forget the name, from a water change. And you can't fix it with another water change. You need mycorrhizae. These little buggers will eat the other bacteria or root decay and then give you more nute absorbtion once they take over the place. The only company i know that sells this stuff cheap is Earth Juice. Ten Dolla. If you can't find it around; you might have to go hygrozyme or one of a handful of others. I've also heard h202, hydrogen peroxide, read up on that cause I haven't used that. That will kill all bacteria in your res. Since I've been using mycorrhizae... I a) haven't had a problem, but more so b) don't want to kill everything in my root area.
First thing mist them with a spray bottle until the goo comes off. Do this over the bath tub or sink or whatever but you'll need a lot of water. You're girls are gonna stress the next couple of days, but I've seen plants recover from this. They were in veg, but if what i see in the pics is what i think it is, you'll need to clean the roots. Have you been using the fogger the whole time? I would raise the water level to meet the cups, thus going straight dwc, add more airstones as already said, and cut the dripper and fogger for the next couple of days until we know we can move forward.
And thats the hard part. Root rot (look up pythium) will cause all these things. But I've never seen it get a hold of a crop so rapidly. There's most likely a lot of dead plant matter in your root balls, so don't be afraid to blast it out of there with the spray bottle. I had one once that I was pulling dead roots out of. Your root mass doesn't look too big so you need to save what you can, but if it looks dead, like leaves, I would remove them. Also 6.0 ph and keep your nutes at 1/4 strength (700ppmish.) There's a good chance they haven't gotten any nutrients in the last week or so, but we want them to be able to absorb what they want when they do get life back into them, DWC will allow this nicely. Your water temp and lights are fine. Like I said this is step one, aside from these couple of pointers, I'm baffled. I've seen this before but not one that took over this quick. Damn bro, let me know how things go... even my head hurts on this one. I'll check back later.

Also give them a foliar feeding at 1/4 strength nutes or less. When you get your nute solution up to the 700 range in your reservoir, put a little of that in a spray bottle and maybe add a little fresh water. They will still absorb nutes through their leaves so thats how u can emergency feed them for now. If you have a product with B1 add that to the spray. It is a destressing agent. You don't have to run out and buy it if you don't have any, but it would help, same with the mychorrhizae, not 100% needed, but will help.
Edit: one feeding for now...they absorb much more through their leaves, so spray until they're dripping right after the lights come on if you can. If they're on by the time you read this, hit em anyway, you're not using HID's so you won't burn them. Just make sure they have time to dry before the lights go off, or mold will follow. Good luck man.

hey, i havent read through every post, but i noticed you said earlier its hard to keep temps down, due to lack of ventilation.
pick up one of these CO2 boost buckets. http://www.discount-hydro.com/productdisp.php?pid=750&navid=30
Run it only when the lights are on.
With the extra CO2 your plants will be able to deal with higher temps, and absorb more nutez,,, CO2 will also give you a little more weight to your buds.

Ya...but 2 of them are just fine...I dont get it?....the 3 that are dying are even starting to grow new shoots........the other 2 are my old mother plants...the moms are living, no probs with them...
I added some peroxide..about 2 hours ago and shut of the top feed and fogger...brought the water up to the bottom of the net pots like you said....and am spraying with very diluted nutes...but no reaults yet...just death....and new shoots....I am baffled?
