Looks like you're doing fine, obviously yield can be better yeah but they look really healthy. You'll get a routine down in a few rounds. I would certainly veg a little longer and get an air-cooled light fixture so you can get em higher, or just run more plants in smaller pots if you can... Most strains I have run double in size after flipping to 12/12 so be prepared for that... Good luck, and nice work with those.
