phototron exp wierd yellowing

i picked up an led phototron, mostly for the light since it has pendants that are absurdly bright. i figured since i was still getting my area squared away i would goof around with phototron until it was all set.
for the most part the thing works really well. not really surprising considering youre saturating a very small area with 320 watts(led watts). i think the light will work well in a larger area with the pendants to help the sides. so far the girls are popping nodes like crazy even on the first leaf pair to show and i cant remember ever really seeing that happen. Anyway, they are yellowing between the veins and i think its a lockout but im not sure. i have some pics so if anyone can maybe gimme a heads up i would be grateful.
