yes
that's a very bad mold / fungus

cut it off or down .. however you choose either way this close to harvest it's best not to leave it
BobBong Reviewed by BobBong on . Stem turning black My outside plant has a section on it where the stem is turning a dark color. One of the side branches had the same dis-coloration on it and started to die. Is this possibly a sign of mold? I don't have any pictures sadly, but it goes from a nice green, to a section of darkness.... any ideas are appreciated, thanks! Rating: 5
