From my understanding ( since I am NOT an expert in cloning) you should take the clones in the veg stage and not in the flower stage though you can. I will say this....hope you know how to clone and have had success with it before and KNOW FOR SURE you can get at least a 75% success rate before you decide to cut all of her branches off or you might end up with nothing. There is a science to cloning that you have to figure out yourself. It is NOT as simple as it is made out to be. Flower the plant itself and practice on cloning until you get it down would be my suggestion.
