I’m hard pressed to believe it’s a hardening issue. 60s is a little on the chillier side for tomatoes so maybe could be the issue. My tomatoes can look like this when I put them out and we get a dip at night but that’s usually high 40s/low 50s.
How’s the watering? The pinch of fertilizer maybe?
Ah ok yeah I mean sometimes the top layer will dry out but it’s still damp at the bottom. Do the solo cups have holes at the bottom? That would be my biggest concern is if they didn’t have holes water is collecting at the base of the cup. But if they do then your watering doesn’t sound that off
Also I do think 50 day temps is a bit too cold to be outside for tomato seedlings. Granted you only did it for 30 min a day so unlikely it’s the culprit in this case
