Am I doing something wrong for my Roma tomatoes

Hey all! First time planting, and I think for the tomatoes they aren’t doing the best.

My tomatoes are curling down currently (don’t mind the old leaves, I overwatered and they got edema.) but everything has seeming fine for over a week and now they are starting to (at least to me) show stress.

Currently, they are in a vented tent, no other ambient airflow but they do slightly move so there must be some wind from the negative pressure
Getting about 400 PPFD
I transplanted them into 4 inch solo cups about a week and a half ago.
I water only when they feel light.

Any suggests or maybe they are actually good 🤷🏻
