WTF is this? Please help

I have no specs... my friend sent me this pic and I don't know wtf it is... please help

Those appear to be marijuana seedlings.

Yeah you need to provide all the specs as you call it.

Trash, bugs, or mold nothing I would want to put around healthy plants.

Ok guys now how about this... why are these clones like this when they come out of the dome....for 2 min... the leaves curl. .. they all have roots

What the fuck? Is that really bad heat stress? Maybe light stress? It can't be mag def at this stage, right?

Your shit looks like it's also getting the fuck eaten out of it by bugs.

I see no bugs...I'm 100% positive... maybe heat stress or light stress... but they are perfectly fine in the dome the leaves will open back up... I'm not at my usual location... could it be from lack of air flow around the dome... maybe no con because co2 is heavier than the air and it's up high by the sealing .... idk... I'm stumped

They are potentially in your medium, if not under your leaves.

You don't need CO2 at this point anyway, and where is your lighting? What kind of lighting?

Did you let them dry out? +heat rises, sudden temp difference dont help either,

Weird. You say this happens with just 2mins of them out of the dome? Toxicity of some kind? Never seen anything like it in that time scale.. Is there anything under the propagator on the floor that could be giving off gases under the heat of that area? Rubber mat or pvc? Just a thought. As pookat says extreme temp diffs?
Edit, sudden RH changes, whats your RH outside the dome?

This pic says overwatering is involved, and that tip yellowing is possibly potassium deficiency due to overwatering, although that may be N-tox. Tacoing is a heat issue. They were too humid and I'll bet the sudden air temp change exacerbated it.

That yellowing really looks like light burn.. Maybe overwatering, light burn, and heat stress, or any combination.

You have over sprayed these babies and leaf curl is a common sign of being over sprayed on warm leaves.
