Thanks man. NGT has helped me make this grow the success that it has been so far. Stick with him, he knows his stuff.
I'm wishing I hadn't spent any money on premade systems as well. The air pump they sent with the DWC system failed yesterday after only a week of use. The whole res. is too small to really be feasible for all 14 sites to be used. I'm much happier with the drip stake system I made myself on the cheap.
As for Humboldt's question about the yellowing, and pests. The pests haven't bothered me recently, since I recently sprayed them with FoxFarms Don't Bug Me. I think I was over watering too, which caused the yellowing. At that point in time, I was hand watering by simply dunking them in the solution. Things seem to be much better on the drip stake system. I do notice the occasional discolored leaf, as i'm still learning so much. Hopefully I will get to a point where I can keep them all green as can be.
