To me your plant looks , how she should look. Your planty maybe need s around 20 ml water per day, no nutes for the next weeks. You can give her more HUmidity in applying an open dome onto her. Cut a plasticbottle in half, get some holes in it and put it above the seedling. If possible gt a humidifier because seedlings loove a high humidity
here is achart wich humiditylevel should be your goal, in dependence of temp and stage of grow
