HELP!!! I've Read ALL I Can and Im Lost! My Plant is Dying (Or May be Dead)

Setup: 12 Plants in Rockwool, placed in flood and drain buckets with hyrdroton covering the base of the plants and the rockwool. Plants are about 24-28" tall.

Problem: Plants put into flowering on October 12th, watered once a day, water fills up to the hydroton level and then drains
Problem: After 7 days one plant out of the 12 looked droopy, so i immeadiately thought it was because it wasnt getting enough water. So I watered the plants just one more time. It never crossed my mind that ALL the plants are getting the same amount of water. 3 days after that, 10 days total into flowering this is what the plant looked like.

Crispy...from over watering? I dont know. I do know that the plants are in rockwool so it is possible that one watering a day should be ok for plants that are 2+ feet tall.
Here is a picture of the crispy plant with all the other plants in the room And as you can see they all look fine (except for yellowing of the leaves but from my research i think it could be nitrogen deficiency).

Solutions: But could someone help me? Im guessing its over watering so i did not water it today...I even stuck my hand down into the hydroton to touch the Rockwool and it was damp but no more damp than the others....so as i said im confused and need help if anyone could direct me to a thread that has information for "Dried, Crispy, and Droopy" leaves

If all plants are getting EXACTLY the same thing and only one plant is showing problems, have you inspected well for pests?

I'm assuming all the plants are the same strain? one out of 12 tho, I don't know could be bad seed. hard to tell with all the plants getting the same conditions unless as said bugs?

Roots in good shape?

I do have mites on all the plants, but they're under control (fingers crossed), I used AzaMax 7 days ago. But I sprayed all the plants with it and did not have any problems with the rest of them.

Yeah they are clones, supposedly they are all the same strain, i got them as a "starter newbie" package

I can't really say, since the roots started to grow out of the rockwool and now into the hydroton so i am afraid of grabbing the stem and pulling it out of the hydroton tearing the roots up. Thats why I was thinking it was probably over watering due to the rockwool holding to much water in.

That screams root rot to me (from overwatering). I would recommend cutting your losses and getting the problem child out of your grow room. Since all plants are hooked to the same res (I assume), it'll be much easier to work with 11 happy plants than 11 happy and one not-so-much....

EDIT: I'd also hit the rest of them with some Hygrozyme (or equiv) to clean up the roots.
