I have three possible solutions for you, but keep in mind I am still on my own first grow, so I may be wrong.
First off, when you describe the cotyledons curling up and in, I immediately thought heat stress. But, according to what I know, the best temps to be at is between 75 and 80 F. So it may be that. Maybe try getting the light a little farther away from the plants..
It also may be the PH. As far as I know, you don't want your PH to go above 6.0... I don't have my bible in front of me ATM, but I think the range you want for DWC is 5-6...
Fuck... I smoked my wake-n-bake while typing that, and now I can't remember the third thought thing I wanted to mention... damn. Sorry man.
Well, I hope that helps... I wish ya luck, man!
OH!! Do you have airflow going through there? Plants need fresh air just like we do. Plants use the carbon dioxied around their leaves within a matter of minutes, and without a fan gently blowing air around they can be stifled and stunted.
I don't think that was my original though, but I better post this now so you can figure things out. Lol sorry for the stoned morning ramblings...
-------------------- My best run so far

Hmm... then I am flummoxed, my good sir.
But I would not recommend using nutes just yet. I think they're a bit young yet for that... I had been told to wait to feed till the cotyledon's wither and fall off from age... you should have at least two nodes of growth before then, I believe...
