Seedlings not growing up???

Seedlings are 6 days old.
Seem to have something wrong.

Light is a 300w LED panel 6 inches away. The seedlings were germinated in a cloner

I don't know if it is the same problem that i got. But in my case there was trouble with heat stress. it was too hot and too dry in closet. it was about 30 degree C and 30% air humidity. since it dropped to 25 degrees and went to 45% they started to grow pretty well. I also mixed a little bit of H2O2 to water. I was told it will help the roots to recover and to get more oxygen. seems it helped, but i am growing in soil.

With the ventilation and using LED lights, I dont think its anything over 75 in there to be honest. I don't know if i over watered them or something.

Looks like mine a couple of days ago. I over-watered them...if these are bag seeds let them be for a couple of days till you see them start yellowing like they're losing water. Then water them some. Mine are starting to recover. (seemed like a dome helped out alot too)

They are feminized Nirvana seeds. I will just stop watering them and hope for the best. I probably have over watered them



Edit
I just threw some saran wrap over the bucket to help hold some moisture in and up the humidity a bit.

what kinda light??? the plant could have gotten damaged when it was exiting from the seed

300 watt LED panel. Plus 2 90w UFOs that are not currently on.

Yeah let them dry out a bit. I grow in soil and I wait till the soil is completely dry, also I have mine in a humidity dome till they grow out their second or third set of leaves.

how do they look now?
