Thats a sure case of bud rot…!
Botrytis the fungus is sometimes referred to as “botrytis bunch rot,” “botrytis blight,” “bud rot,” “grey mould” or “gray mold.”Carefully remove and discard all buds with bud rot, as well as nearby buds - this is incredibly important if you don’t want to lose the whole harvest! Don’t let anything any of the rot touch other parts of your plant.
they need less dampness, drier air and warmer temperatures. If you can improve the environment, you can allow the plant to continue ripening after you’ve removed the infected buds.
As for your plants_!! What’s eating them?
You can most likely find this at your" r local hardware. Store Do not get the DE for swimming pool s
