Hi, Jaden.
Nice sized seedling for just two weeks old!
I would also initially think you over watered your plant. Yet, upon enlarging your pic, I see no signs of excess watering in the drip trays of your setup. I now consider that perhaps your plant was over dry and simply needs some more time to rehydrate, but could be wrong.
Here is my current seedling starter setup.
I use bottom watering with a few squirts from a plastic pipette. Pick up your pot. The weight (dry vs just watered) is also a good indicator of moisture content. Easy on the watering the next week and it will likely recover.
