Ok, for the last week these seedlings have continued to yellow and stagnate, with little or no growth at all. I don't know if it's overwatering, underwatering, or heat. We've still had some 75 - 80 days here in SoCal. The PH is fine and I am using a single 95w CFL that puts out about 6000 lumens for this seedling stage. I intially had it only a couple inches from them but it seemed to get warm under the reflector hood (up to 90f) so I moved it up a couple more inches. Maybe these bigger CFLs run a lot warmer than the small ones and i need to keep it 5 - 6 inches away??

Anyway, one of the seedlings was obviously doomed so I did an autopsy to see what her roots were like and to check the soil dampness etc. The soil easily came out of the pot, was slightly damp but not clumped at all. The odd thing was her root was constricted, shrunken, and hard just below the soil level..very tough and leathery. Can anyone identify this problem???

I drew a picture I hope might help:
