1. You're using nute soil, nutes and superthrive.. Bad combination. Seedlings are easy to burn into the first month of growth. You want to wait until 4-5 nodes before feeding.

2. Do you have drainage holes in the bottom of that cup?

3. The PH of your water fluxuates way too much. 5.8-6.5. You need to be staying at about 6.5-6.6 consistently. For soil grows your ph range is 6.3-6.8.

4. You may want to repot very soon.
