Plant gone limp! Was fine yesterday...

So i have been growing this plant in a dwc system for about 16 days now and things have been going great! Doing 18hrs on and 6hrs off under 4 CFL bulbs.

Have been using fox farm liquid nutrients and the ph has always remained perfect.

Today i came home to find my plant still very green but limp as could be. Some of the edges of the bigger leaves have slightly curled up.

I AM THINKING that it may be over watering... I have 2 air stones under each plant and one big one down the middle of the rectangle container... over the past 3 days the water level had dropped causing the air stone not to produce as many bubbles... which leads me to think that it might be over watering...


I have added more water and the bubbles are back to normal
??


Any second opinions????

What with everyone in this thread and not posting details?
how often do you change ur res, what's the PH and the EC at. temps? humidity? cummon dude.
its probably a build up in un usablt fertalizer that has built up into the solution you are using... you should change it every 2 weeks to prevent this from happening.

looks like its over watered. im no expert, nor do i use hydro but either too hot temps, too much water or maybe u just need to change the res.

if you are in dwc you are not overwatering it .. that is not possible.. maby there is not enough oxygen getting to the roots.
take the airstone out and clean it with alcohol and a toothbrush, rinse it good.
if not change the water to clean plain water in the res for a day or two to cleanse the plant a little bit. and then on the evening of day 2 give it some nutrients again.
everything should be back to normal in a few days.

the ph stays at 6(ish) but i try to keep it as close to 5.8-6.0 as possible. Temps stays around 83 max and gets down to 72 at night.... not sure on official humidity but id say its normal for texas weather... I change the water every week.... last week i flushed the rockwool with some plain water because there was a minor salt buildup.....

id prefer a pH of about 6.3-6.8
then again i grow in soil, sorry if im of no help.
im just giving my 2 cents, whether it helps or not.
