I would try moving the plants closer to the lights so they don't feel the need to keep stretching. My lights (3 26w clfs) are currently set 6 inches above the plants and I would put them closer if I could.
I'm interested to watch your grow as I have some ak47 auto fems to try out in a future grow.
mine just officially started today as well 2 days old right now though. get them CFLs real close I have mine probably 3 no more than 5 in away. get a lil computer fan blowing over the plants, this will allow you to get the lights even closer, since it helps keep the heat down and the stems strong
So that is Just a big dwc? Or are there pumps in there?
As others said move the lights as close as possible and add a fan.
For hydro (and especially dwc) make sure your water temps stay below 75f max and even better if under 72f.
Higher water temps in dwc is asking for trouble. Good luck!
Yup, yup, keep those cfl's close! That'll prevent stretching at an early stage.
Another thing that I see, is that you need to cover the holes on the lid that you aren't using! This will prevent anything from contaminating your precious nutritious water!
Another suggestion, maybe move your plants towards the center of the reservoir to utilize the light that you have.
My grow is somewhat similar but without hydro.
