Has anyone ever had a plant start budding her firs...

Your girls look perfect. Not sure why starting to bud so soon after you flipped her would be a bad thing. She probably was eager to kick out some big buds for you. I see a couple of older lower fan leaves starting to yellow you can just cut them off it's normal they did their job. Some growers will remove the leaves from the lower 1/3 of the plant including any tiny buds that will never get enough light to amount to anything. You can do this over a couple of weeks if you don't feel comfortable doing it all at once. It will direct more of the plants energy to the upper buds on the branch. Good luck with your grow your going to have some tasty buds as a reward for your hard work.
