Lose the plastic bags and make sure you are letting the soil dry back between watering’s. Want several drain holes in the cups if you can.

Two items to address:

- Dryback/drainage: leaf curl upwards often signifies the plant is too wet. The reason it curls upwards is to expose leaf stomata to expedite transpiration.
Drainage holes are key. The plastic bag humidity domes will retain a ton of moisture, probably too much for a small rooted plant.
Unless you are in a very dry climate the use of domes is mainly for cuttings that do not have a root system to support them.

- Calcium: leaf deformities, particularly along with lower leaf yellowing, more often than not signifies a lack of calcium.
This is a small plant so if a CaMg supplement would be used, use it half the recommended dose, or even 1/4.

These autos are popped from seed 2 weeks ago
I am using fox farm ocean forest soil. Light is 100w led. 2-3 feet high.
I have plastic bags over the plant for humidity. Temp is 78-80 degrees.

The major issue here is that it is an auto j/k
But seriously though it's very overwatered, let it dry out. If you stunt an auto you are SOL however. Might want to heed the others advice while starting a new seed.

toss out bags will fix it self
