looking a lot better!:thumbsup: My guess is if u follow the scientific method, small one step changes, u will be able to get these ladies to optimal growth.
It seems that hydroton doesnt work with aero until the roots clear the rocks. Reason being once the solution hits the rocks, its no longer in its micro form, completely rendering the system useless, and if ur water periodically it may not be enough for the roots, Hydroton is really tricky. The fog probably cant even penetrate the rocks. I think ur well on ur way now and have most of the hard stuff under ur belt.

I usually have droopy leaves from over watering in the first couple weeks of veg, and literally over night around the 3rd week they pick up and never droop again. So it's kinda an art form getting the feedings right, but with hydro over watering isnt to big of a deal because the roots usually get enough oxygen anyway, it seems to me that with these systems over watering is far better then under watering as long as the roots get oxygen.
