make sure to give them at least 1 week if not 2 after a transplant, make sure they have really taken root in their new larger home before flipping to flower, no use transplanting then putting them right into flower, as rose said they dont really gain much root growth in flower, the light spectrum is wrong for rooting. so make sure they have stretched into the larger pot before flipping, i personally prefer at least 2 weeks after transplant into flowering pots/bags, they usually at least double in size once they really take root in the larger pot. so if you want that extra ounce or 2, you might wanna just leave them for another week or so. but they do look really nice, short and compact, my personal preference!
