Leaves are mangled and weird looking

Nothing to worry about, alot of seedlings tend to do this. They will grow out of it.

Hey, I have had a few that way, some from a very low humidity and another with light stress. Typically they've all outgrown it eventually, the autos had a harder time because their clock is ticking so any slow down was rough . I see you're running a 24 hour light...I always felt like all living things enjoy some rest. Possibly if you have multiple plants with this twisted leaf you might consider bumping down to a 20/4? Or possibly humidity dome cups over the littlest ones for another week or two to boost their RH into the 80% range. Good luck with the grow, hope they straighten out soon.✌️
