Cloning Flowering Plant

Ok I know you should take clones before your plant starts flowering, but can I trim the buds off a plant when its finished and clone it from there? If so do I put it in a vegetative nutrient cycle or a flowering nutrient cycle?

You can actually take clones from a flowering plant and put them back into 24/7 or 18/6 light and it will revert back to vegetative growth

You can also keep the plant you have and revert it back to veg state after you harvest, just be sure to leave a little of the lower buds on and of course some leaf structure and move into 18-6
