Yeah its looks overwatered.
Just chill and use less water.
Roots doesnt like to have a contact with water all the time. Once roots feels lack of water, they got more oxygen which they really needs too.
And, of course, thats makes them spread over the soil more efficient, just because of searching for water, like in nature.
If ur using humidifier, just turn it off to make higher temp, which will dry soil faster.
But make sure it wont burn that girl
Dont do too much at this point, let her rest and u may add those bacteria.
For nutrification is too early, use some roots booster now, but vege fert half of suggested dose when it feel better and start normal growth
