hi, just started my first grow. i'm 2 weeks in now, started from seed. recently the first 2 leaves (not the cotyledons) are turning pale/yellow, but the new foliage looks nice and green. i know the cotyledons are supposed to turn yellow and die, but how about the 2 leaves that come after? is this the first sign of nutrient deficiency, or being root bound? over/under watering? enviromental problem? this is happening on all 6 seedlings. today i transplanted them from 16oz solo cups to 2 gal pots. perhaps they've used up all the nutrients in the solo cup? there were roots coming out from the bottom of the soil, and a few out the sides.

indoor. closet box
original organic sea soil mixed with perlite
run off ph is around 7
tap water thats been sitting out for a few days, ph around 7 as well
i've been keeping the soil moist by just misting the top every morning out of fear of over watering
no nutes
8 23w daylight cfl's diy reflector about 6" away
lights are currently on 24/0
around 28 to 30c (86f)
40% humidity
6" duct fan for exhaust. small computer fans for a breeze directed at plants, 2 fans blowing air up at the lights for cooling

any help would be very greatly appreciated!!!
