You will probably have to chop one way or another ….. you have necrotic sugar leaves entering buds.
Not good at all - that can lead to inner mold and necrosis. If you take it down for harvest , I highly recommend breaking all colas down .
That way you can further inspect inside. Forget leaving whole colas for pics - concentrate on what that dead leaf has been doing inside buds.
Besides , there are no fan leaves to keep plant going. Looks like somebody got too anxious with trimmers and pretrimmed.
