Heya, that looks like heat stress.
You say the temps in the ROOM are 75, but what about the temps RIGHT UNDER THE CFL?
Oh yeah, and avoid misting sprouts. They don't like it.... mmm... pythium wilt!
A good way to ensure ample water and humidity is to put them in a plastic, not metal, tray and water into that and watch as the water gets sucked up. When they stop sucking it up from the bottom, that's plenty of water.

Good luck!

OH BTW I'm a huge fan of flourescent t-12 cool white TUBE lights for seedlings in the early stages. They run quite cool and I've never had heat problems, although I HAVE had those problems with both CFLs and my new wave T5... It's just way too hot for seedlings to be closer than about 3 inches or more.
stinkyattic Reviewed by stinkyattic on . so my sprouts are dying again.. pics inside http://www.lifeinwidescreen.com/siihp/sprout2.jpg.jpg Had two good looking sprouts.. then all of the sudden they are shrivelling up and dont look so good. This sprouts stalk looks great, but now its leaves dont look right. It's first real set of leaves always looked a bit odd.. The other sprout i had looked perfect until yesterday. I didnt get a pic because its so far gone now it would be useless.. I cant figure out what i'm doing wrong. I test the ph, its slighty below 7.. soil Rating: 5
