Harris7 - I have the identical problem happening with my seedlings - you can see the pics of them here: http://boards.cannabis.com/showthread.php?t=83485 - they have not grown at all in the last 4 or 5 days and the small round leaves are almost completely yellow/white today. My temps are nearly the same as yours (about 75 to 78 in the grow closet - 85 directly under the reflector. But a big difference is that I am using a 125w CFL about 3 -4 inches from them. I guess it coud be heat but I havent seen anything in the threads about CFL's and too much heat?

My biggest question is how often you watered them? I am thinking it was overwatering for me so I quit watering them a couple days ago and still no difference. I am sure open to finding a definitive answer so I can avoid it with the next attempt.

Just because I seem to be stumbling on my first attempt, my next try will be with some freebie TroubleMaker seeds, till I get this indoor thang down.
