You expect an informed response from that?

Try providing this..

Soil Growers:
1. Are you growing from seed or clones?
2. How old are your plants?
3. How tall are your plants?
4. What size containers are they planted in?
5. What is your soil mix?
6. How often do you water and what type of water do you use?
7. What is the pH of your water?
8. What kind of fertilizer do you use and what is its NPK ratio?
9. Do you foliar feed or spray your plants with anything?
10. What kind of lights do you use and how many watts combined? (HPS, MH, fluorescent, halogen, incandescent "plant lights")
11. How close are your lights to the plants?
12. What size is your grow space in square feet?
13. What is the temperature and humidity in your grow space?
14. What is the pH of the soil?
15. Have you noticed any insect activity in your grow space?
16. How much experience do you have growing?

Without more information, I’d go with overwatering.
in future try to match pot size with plant size. Looks like you have a gallon or two felt pot there for your seedling. Next time your at the garden store see if they have any 3in x 3in.
