Yes, it is entirely possible to clone a flowering plant. However, it is a little harder to do so because you must switch your cuttings hormones from flowering and revert back to vegetative. Can I ask a question first? Is this one of your first times attempting to clone because if it is then I would not suggest trying to clone a flowering plant. It is just better to leave the bud on and let it flower. I would have at least a couple grows worth of basic cloning before I tried to clone from a plant in flower.
