Looks like for 1 day growth they are really tall.

I think quite the opposite happened.
Cfl was so weak they stretched for it and can't support themselves now.

Could move led closer (24w is still pretty small) and try to top up pot with more soil to help support them.

From seed I germ in water. Then to soil/perlite mix under 80w T12 florescent (4' shop light) about 1 inch from the soil/ seedling.

No need for a dome with a seed. That's what the tap root is for :) Just keep your soil barely moist for now.

Get (and keep) your led close. Or better yet use it with the cfl.

If they won't stand up repot them in a solo cup and bury them half way up the stem, it works great. Do you have a light fan blowing their way to help strengthen? Move the light down so they are not trying to stretch so much.

Its not like theyv flopped or even look like they might the leaf pointing dwn is as rigid as the 1 pointin up
Ahh couldn't see that.
I'm on some autos now and I had 1 that came out with 1 leaf fused to the stem pointing down.
Had to do surgery and separate them with a razor day 1.
Needless to say she's my problem child and runt out of my 8 @ day 41. Could just be bad genes maybe?

Looks like overwatering but could be nute burn, pH stress, or just stress from the clay pebble you mentioned.
You mentioned coco and clay balls, is it a custom blend or a pre-made mix?
