Overwatering. Even in bubbleponics it is possible to overwater, if rockwool is set too low in net. Your rockwool should be dry, only when u squeeeze it your fingers will get wet.....

Yep your CFL could DEFINITELY do that. I ruined 12 plants about 7 weeks old because I decided it was a good idea to mist the plants with distilled water while the lights were on. I left the house went out for an hour, came home and they looked 30x as bad as yours, it looks likes you got lucky. I use four 300w tcp cfls and 18 100w daylight cfls, I basically ripped the water out of all the plants lol.... Now I learned my lesson, I only spray them 2-3 mins after lights out.
