King looks like a good discrete size for a Gorilla Cookie in a 1 gal pot. It is in preflowering. Kong is a runt. She is much smaller than King but in a 3 gal pot. It is frustrating. The overwatering was probably a single watering session. But she is still preflowering so hopefully has a big stretch.
Both have been shifted into the flowering tent with the previous grow (Three Sisters). But Kong is going on a stand to lift her up to the light.
