Also. Why do you have a little pot inside a big one. That run off will build up if the roots can't expand Cut down the center of those and pull them up (the smaller pots) they aren't helping pal.

Hey pal So, pick pour points.. away from the stem. This will allow the substrate to breath and the roots will reach through the soil for moisture. The quicker you can get root expansion going the better The pheno itself looks like its struggled a wee bit. Possibly from lack of water (dry soil)..it should be more wet. Soil won't reach out into dry soil.. Generally a few 100ml every couple of days. Some people feed heavy once a week. You can do many different ways. There is no set number rh, temp (environmental conditions play a major role also) You can give more it looks too dry for it's age. The roots should be expanding underneath but only do so (reach out for moisture) Good luck

Photos are more resistant to mistakes and forgiving. Good Luck! Good answer by Organoman

You don’t want to overwater them; the plant will tell you what it needs. Check if the soil is damp just below the surface—if it is, hold off on watering. For 1-week-old seedlings in a 0.6L pot, small amounts of water (around 50-100ml) are usually enough to keep the soil lightly moist without overdoing it. 🌱
