Need help understanding what went wrong.

The seeds are about 5 years old but I kept them in a cool dark area. I germinated it with the paper towel method then planted them about a quarter inch down. I planted 3 seperate pots. Did I over water it? I had humidity issues (too high, at 80) for the first few days. Resolved it on day 5, today is day 7 and I uprooted one.
