Hi SmokeOn, I am on my third DWC grow now, with the previous 2 being pretty successful. On my second grow (during the summer) I noticed a problem that sounds similar to what you are encountering.

First thing is that in DWC you should aim to keep the pH between 5.2 and 6.2 (I like to keep mine around 5.5 to 5.6).

The other thing is nute temparature, I found if it rose above about 25 - 26 celsius (about 77 to 79 deg farenheit) it caused problems with the plant like leaves curling and going brown and crispy. The way I got round it was to fill a plastic bottle with water, freeze it, and place it in the DWC bucket to reduce the nute temps (leave the lid on the bottle so it doesn't dilute your nutes). Put a frozen bottle in each day for best effect.

So I would check your nute temperature and if it is higher than say 75 deg F, add a bottle of ice and see if it helps.
