There’s nothing you can do to speed it up. You could start watering around the plant, not at the plant. You should have a ring of water around them so those roots need to go out and search for water. The way you’re doing it, they’re drowning after you water them until the soil dries out a little. Those pots look small so you’ll probably have to transplant but I would wait a couple weeks or you’ll likely kill them trying to now. When you move then, use better soil in the next container.
You’re going to have small plants this grow but it’s your first and we’ve all been there. Plus they’re autos so even if everything was on point they’d likely still piss you off😂
