First of ALL DON'T USE FERTILIZER PLEASE!
This Yellow means they are dying out from DRY AIR, and maybe HIGH TEMP'
Use wet towels, bowls with water, and spray/moisturize(how do you write this???) to get them look better in a few days!
Temp under 30C is OK 23-25C would be best but WTF sorry I'm a stupid German so I don't know about degrees in F just that more than 89 mean's I'm Sick^^
I have some Ideas to make this grow work out... Switch off all those CFL but two of the daylight ones...
Take one of your Seedlings direcly under one CFL each at 1,5inches/3,5cm distance!
In a few days, Switch on 2 CFL's per Plant, and put them on about 5cm(about2 Inches) distance... Later you Switch on more and more if you upload pictures maybe I can guide you a little.
The Point is, first of all this will bring down the head, and stop the waste off energy!
The air when it not heats up this much gets not as dry as it seems to be now! Another time I repeat, Spray water an them, use bowls cups and dry towels to put them around your plants!
Still DON´T USE FERT!
edit: I see your not using cups at the moment, what ever it is, when you can see roots come out of it, put it in a at least 3L(100OZ) cup with good soil!
For shure you should use fans or at least one fan. Plants should be mooving, but don't let a big fan blow directly on them all the time, and not too close, 'couse this can dry out the leafs like a fuckin' hair dryer.
Peace
