Bud rot is caused by the Botrytis Cinerea fungus which affects the cannabis flower from the inside out.
The fungus is easily transferable through air or water. If your bud becomes mushy you need to open it up to check for grey mold.
Bud rot also exists in other plants and is often referred to as “grey mold”, “botrytis blight” or “botrytis rot”.
