From seed is hectic if you havnt done before. There can be a good week-2weeks of 'stalled growth'.
-When the seed pops, it grows a single taproot that will first grow straight down until it hits the bottom of the pot, then start throwin side shoots. This is why a smaller cup is beneficial.
Leave em be, and let em dry out before watering. They gotta work for food if you want em to grow.
