Skywalker Ghost× Triangle Kush seedling HELP NEEDED

My girl was started on the 29th of June. Shes in roots organics, under a 20/4 light schedule. No feeding yet. Temps 76-81°F She is beginning to yellow around the edges of her leaves. Outside for better pic.

This is healthy cannabis. If anything water less and when watering water away from the stem zone to encourage roots to grow TO the water. I.e. the edges of the solo cup. This will suits you up well to transplant.

You think overwatering? Today was the 2nd watering, with about 10-15 ml of water.

You’d be extremely surprised how little water the plant needs. It can be very self supporting.

I’d look into bottom watering

in your stage you’re trying to get the roots to expand to the plant to prepare for transplant.

rest assured, the plant will tell you if it does not have enough water. As of now, just let it grow.
