My ultrasonic/bubbler setup

Hey,

Things seem to be going pretty well, here are some stats and pics, comments very welcomed.

(Plants on the right)
4 weeks in to vegging
full fertilizer solution
1 ultrasonic fogger
1 18 gallon air pump
3 24w 5400k CFLs
1 24w 2700k CFL
balanced pH
about 75 degrees

(Plants on the left)
5 days into vegging
no fertilization
2 ultrasonic foggers
4 24w 5400k CFLs
hydroton soil medium
planted in rockwool


Let me know what you guys think.

Also, about 5 percent of the roots seem like they are dry/dead, does this mean I need more foggers?

Thanks

BTW, one plant is Medicino Kush the other is Purble Berry Bubba Kush

One fogger is plenty for that setup...Raise the water level if their drying out.
