Help my seedlings live!

Hello all, first time grower here. Last night I discovered a slight mite problem just started from some used grow equipment I acquired. I went and sprayed my seedlings with some habanero pepper spray from a thread I saw and left them in my bath room without light for around 24 hours with fans on so I could clean the room and equipment. They seem to be turning a dark orange to black. Is this a fungi? Can my little ones be saved? Please help

spraying anything on seedlings is dangerous, they're at their most vulnerable at that point. what an adult plant will shrug off will fuck up a seedling.
its not a fungus or anything else, you burnt them with the pepper spray. they might recover, they might not. if they do recover, it'll take them at least a couple of weeks, they have to store up enough energy to put out some new leaves. that might take them a little while with the limited leaf surface they have left.
don't spray a seedling with anything. let them get bigger. you might have had mites, you might not have, but now you have a real problem to deal with. would have been better dealing with the mites for a couple of weeks, till the plants could take it.
and look into some spinosad. pepper spray will work....on bigger plants. spinosad won't burn a seedling like that. i'd still go light with it, but it won't do that.

How strong was the pepper spray? Those look about done though. Not much left of the leafs to get back into good shape and thats a LOT of stress to put a seedling through. If you have other seeds or didnt go broke on those, I'd suggest just scrapping those and starting fresh with new seeds and a clean, mite free room.

i hate to give up on a plant. i'd start some more, but i'd set those off to the side and let them try.

Ah I see. This is regrettable but at least it's a learning lesson. Probably just restart with some clones to get back to point I'm at. Thanks for your help!
