Help with HPS Light Growing

Hello! I germinated 3 seeds, which then i placed on their final 2.90gl buckets. Good soil mixed with some nuts. One of the seeds got off great and is still growing nice. The other too i notice are struggling...or maybe im anxious, here are some pics. The seeds are auto and the HPS light is 400w. I watered them enough so they dont flood.

Distance from lights is around 19 inches. I now have moved the two little seedlings further back around maybe 25 inches...advice ?

to young for nutes and what soil did you put them in?

lol was going to say, is that out side dirt or cactus soil

They look pretty fried.. Seedlings do just fine with no nutes you jumped the gun should have laid back let them grow a bit then feed them.. Good luck.

Hey, i have to agree with delstele on this one, just to much food and maybe even to much light. I've personally never popped seeds under HPS so that might have an effect on them because they aren't getting the spectrum that they need as little ones so that mixed with food has probably stressed them out and they are giving up. if it was me i would flush them so that you know there is no food left (measure E.C if you can) and try and get them at the right height for the light (far enough away that you cant feel heat from the globe near the top of the seedlings. Good-luck
