It doesn't look like bud rot but yes, another type of mold. I would leave it all out to dry at about 50% RH for like 4 - 8 hrs, pop it in a jar with a little hygrometer and see where the level is at. If above 75% still, leave it out longer, pop it back in the jar for an hour or so and see where you're at... keep going until a bit under 70%. Then pop the lid daily for an hour or so and repeat the process. I would cut out any leaves with white stuff on it and toss it. Keep a close eye on it.
