whats the temps on the top of the leaves? not just room? looks like a combo of being hungry + being burnt by the lights.

almost looks like nute burn, but if this is the first feeding, then definatly not it.

however, i would dilute the nutes a little hald str is pretty strong for a seedling. 1/4 is safer.

not sure how much calcium is in the nutes you added as i'v never used them, but it might be more worth it to get some cal-mag and add that

if you have a ppm meter, use it. keep the ppms lower than 250 on such a little girl.

i cant tell from the picture if they are curling up or not... if they are... try to get a bit more of a breeze on them..

if its just yellowing and dying.. its a good possibility its either a cal-mag or nitrogen issue.

The one with more leaves is curling up but not the other one that is effected, and have no ppm meter and its a 3 part micro grow bloom from stlh yhdro cantt spell, have nutes and items comin in mail wed but was in a panic put those organic nutes in yesterday

dilute the solution soon as possible... first pic looks like nute burn, second pic looks like a deficency.

i think you may have jumped the gun on planting.. always make sure you have everything you need first.
