When is the earlist you can flower after transplanting? Seem very happy after a day but I have read that it best to wait a week?
You don’t have to wait any certain amount of time, but it is best to give them a few days to spread roots into the new container to fully take advantage of the size increase during flower.
I recommend root stimulants/ B-vitamins for 7-14 days and then a flip if everything looks healthy, happy growing!
