My plants taking a turn for the worst

Set up
600 watt HPS 12/12
DWC
micropore airstone thing
20 watt commercial airpump
a fan

My girls have been the blooming room for 4 days now. and they look like they are dying. I changed the res, using fresh nutes. 6.5 PH

Only one of the plants still looks healthy

They are in a larger room now so the average temp is a bit lower.

Here are the pics. let me no what u guys think.

Looks like to much H2o or not enough fresh air.

I just switched to a commercial air pump, and used some h2o2 just in case it was

i switched it back to the old airpump. prob won't help.... Is it possible my plants have a disease?

I dont know much about dwc but I think if it were a disease it would show different symptoms. When I use too much H2o2 my plants dont like it and they droop. i would stop that and go back to whatever air pump you were using. Give it a break from the H2o2 as well.

That looks like a very healthy plant other than the droop. My money is on the H202. I only use that stuff every now and then. And very sparingly, like 1/2 ml per 10 gallons. Maybe 1 ml tops. Some guys only use 5 drops. I don't know how much your using but start there. What are your ph and ppm levels like?

PH is now 6.7
PPM 880

The h2o2 was not added til after the drooping. i moved them to a tote with no water for a couple hours to see if it is overwatering.
