Flower grows on branches, if mine and it's not and you paid for it so it's yours to do as you see fit, I would have tried to grow some branches before trying to flower, as a clone it's a cutting from another plant and you want to turn it into another plant, it's already shocked from being cut off the mother, you have the right idea with the
fox farm, but flower does not grow on fan leaves you want to have some branches that's why you grow it into another plant it's a photoperiod you can grow it as large as you want/can then you decide when to cut the cycle and flower, I don't do clones I just pop a bean, however I do clone my houseplants and give them away as gifts, I hope it works out for you, I would recommend
Atami Bloombastic for a flowering agent, good stuff.
