Hello.
Don't stress, lots of seedlings have weird starts. Drop the ph down a couple points, definitely raise your temperature, and keep up the good humidity and she'll pull through. Even though your pots are fairly small....it's still big for a seedling and the oxygen in the 2water gets used very quick so then the soil until it dries a bit is typically low oxygen, and little roots don't like that. So probably once that soil dries a bit more you'll see improvement.
Happy growing .✌️
