Holy shit we saved one of them, the other one idk. Thnx everyone for chiming in. Seedlings for me should be around 5-7k lux and that's what i had these under, idk what could cause a stall like this ive never seen this before. Wasnt root rot or those coytledons would be yellow by now, that's why it was such a mystery.
I went from 6k lux 15/9 lights(yeah plz dont start in on me about that) to 12k lux you guys are nuts, but it worked, maybe a new trick in my bag idk.
I dropped it back down to 7k lux now that ive seen movement.
So if anybody else runs into a seedling stall, try a lux boost, but you gotta watch em, dont walk away for the entire day and think they'll be fine.
