Hey man just saw your response.i would do the same,wise move.no need to take risk because that definitely looked like rot to me too.i think rotten bud would smell different than a fresh one if most part of the bud was rotten,yours was a little spot.Ive never had rotten buds so fortunately,always get the air circulating well,better wind stress than mold! Deeper parts of my buds look like this after being in jars for months,i know that is because trichomes are getting oxidyzed and potency dropping slightly but new cut buds should look fresher
