Update! The two Cinderella have perked back up quite a lot. The mixed seed unfortunately looks worse 
fingers crossed it recovers.
@anon20530495 you may hold your title for now! I maybe coming for it again once I start watering 
Getting them outta the solo cups was the right move in my case, they look much happier just overnight
@AzSeaindooin420 thank for you explaining that, I bookmarked it for in the future! I removed the humidifier an will see how they fare. Since removing the temps raised into the 80s an humidity dropped to 20%.
Is the humidity not that important or only because my plants were over watered? Should I put it back in the tent at a later date?
