i dont see a fan sir.. is there air blowing across the plant all times??
as well you PH could be dropped to 5.8...
they look a lil burt from le nutes yes butthe cfl's could be heat stressing them as well.. IMO you should have a fan on them 24/7

I have a ceiling fan on at all times... will CFL's burn seedlings?...dont feel much heat from them....do I need a fan for seedlings?...I thought when they get a lil older i can start using oscillatin fan..... thx for response
 
Yes you need a fan for seedlings.

You also need to drop the pH to 5.8 after you put a weak solution of nutes in your rez.

If I have a plant in my DWC I also have nutes
 
Fan is a must even with cfl's. Even thougt it may not be hot but they need GOOD air circluation! and it helps to thicken there stalks. Well be happy if you thicken their stalks now for when they get older :) If your gowing to run nutes now use them weak. For about anoher week so they can get going back to full strangth and run what you need when they get back on there feet :p
