Help identifying problem w/ seedlings (pics)

First grow here. They are about 1.5 weeks in soil. I noticed it originally about ~6 days ago when 2 of the 5 were sagging and looking a little wilted. I now see some sort of yellowing in between the veins. Two of the plants look pretty crappy with sagging. Two others are doing pretty well and the last is sort of in between.

-Strain: Northern Lights

-Soil: Fox farm ocean forest

-Nuts used: None. Everything I read says not to nute until 2+ weeks and the FF bag allegedly says even for 4 weeks so I'm kind of doubtful about that yellowing being nute related(?)

-Watering: I tried to be on the conservative side after reading so much about nubs overwatering. It is quite possible I underwatered instead lol. I have ramped up the water a tad, letting some come out the bottom, and watering only every 2-3 days as the upper soil just below the top starts to look dryish.

-Air: Temps is 81 atm (more below under Lights). Fan blowing gently downward. The plants shimmer every so often in the breeze and are not being blown over or anything. Humidity ~35%. I plan on raising this up to ~50 in the next few days along with lowering temps with an evaporative cooler and additionally a humidifier should it be needed.

-Lights: 2 4ft T-4's, 6500k. Around the time time the problem started, I had turned on 4 additional CFL's of the spirally-bulb variety most people seem to be using and the closet got around ~90. A few days into that I turned most of that off to get the temp back down, plus I don't think they need that much light atm. I had the bulbs 1-2 inches away so.

I'm thinking my problem can really only be: underwatering, overwatering, light burn if that's possible from the CFL's being 1-2 inches away at this age, temperature, or some combo of them. I've been doing a ton of reading/research but I am alas still just a nub. Any thoughts/ideas are appreciated :)

First two are of the same plant, the one that's in-between health-wise. Note the wilting and yellow color on some parts of the leaves. Edit: These were watered about 12 hours before the pics were taken:




Last two are the sad saggers:

Well some people on another forum said they couldn't say anything was wrong with them until they get a bit bigger. I'll just keep trying to stay away from them I guess...

*runs over to visit them*
