Hey hungry Ray, you like the technaflora lineup? I don't see many people using it, especially in the DWC. Works really well for me, though I've never tried anything else... I don't know if I want to though, I'd be choked if it didn't work out as well. The techflora nutes really seem to flush out great too. I've never seen whiter ash on a J, smokes like a dream.
4tatude, Looking pretty good man. One thing that might help, is raising your water level right up near the bottom of the cup. The really thick roots that are in your hand "cord roots" as they're called, are just for supporting the small feeder roots that are in the water. If you have the water level higher, you have more available nutrients overall, and a larger area for your feeding root mass to grow. Growing thick roots to support feeding roots wastes some root growing energy that could be going into making more feeding roots, which in turn will make more buds!
