Hey everyone! I'm trying my hand at direct sowing tomatoes, but my seedlings are really struggling. They haven't developed true leaves yet, and the cotyledons are starting to fall off. I've been bringing them outside during the day and taking them in at night when it's cold, but I'm starting to wonder if I should have kept them indoors altogether. I'm located outside of Pittsburgh in zone 6a. Any advice?

When did you start your seedlings? I'm in zone 6a/b too. I started mine over a month ago on a heat mat with a grow light. I only just started putting them outside a couple weeks ago. Just a heads up, you're likely not going to have success with direct sowing tomatoes since the season isn’t long enough. But don’t worry! Your local garden centers should have tomato seedlings in the next few weeks if you want to give that a shot!
Check out these resources from your local state extension office; they have some great info on planting tomatoes and other vegetables:

Remember, USDA plant hardiness zones mainly reflect winter cold; focusing on growing seasons, first frost dates, and planting calendars is much more effective for planning! Happy gardening!
I started mine on 3/25. Maybe I should have done it earlier!
