Since you where growing organic but still using fertilizer I recommend at least a week flush. When you flush it improves the smell and taste of buds plus a proper dry and cure. How to flush easy get some distilled or ro water and flush soil that's it your done. Give plain water from now on till harvest. Another tip you still need to pH water when flushing. Some growers say not to flush when organic. That's only true if u haven't feed plant anything but water it's whole life not any kind of nutrients no matter if it's synthetic or organic. Only way to not flush is grow in living soil/super soil.
