Don't let me kill my babies! They are turning a very light green!

And I can't find the answer. The sprouts seem to be growing fine, but are turning a very light green and spreading fast.

About 3 days ago I switched from CFLs to 400 HPS. The light is air cooled so I have the plants within 5 inches of the light, but it stays about 82 degrees at the most. Humidity is very low. About 40% after a watering and then it drops to about 20% as they dry out. I have an ultrasonic mister in there, but I think all the humidity just gets sucked right out. Light burn? I raised the light to 12".

2.Growing Indoors
3.Watering every 3-4 days with a total soaking with RO water- no nutes at all.
4. 50% Pro-Mix, 25% Miracle Grow Perlite, 10% Lime, 15% Worm Castings.
5. These plants sprouted from seed about one week ago.

No, still waiting on my meter. I was hoping/assuming that since it is RO water that I would be ok.

looks like overwatering,if youve been giving them tapwater,have you been letting it sit in a open container for 48 hours before watering,i wouldnt worry about the humidity too much,as long as you mist theyll be fine,,as they get older the humidity will increase in ya grow room,,,,,,,,,,,,,,peace
