bud rot on one bud!! what to do?

Hi everyone,

I found this tiny rotten bud on the side on one of my main colas. The rot is still in the beginning and i cut the affected bud immediately. My question is: should i cut this main cola as well as safe measure or no? here are some pics.
Also is this botrytis or other type of mold?
thank you for all your help guys and ladies.

The rest of the plant is ok??

Are you sure there's not a catapillars in there?

Nope, I haven't see any caterpillars in there or even ever on the plants. Only japanese beetles/ stink bugs...etc
