Hard to see from the close up (not quite focused, 87kb), but looks like bud rot to me. If you harvest bud rot, when you jar it up, later it will smell of strong ammonia. It is a mold and frankly I would be skeptical about inhaling mold microbes into my lungs. Why take the chance?
I come across bud rot all the time. Florida reaches humidity levels of 80 - 90% depending upon local conditions for three months or so in high summer. That's 24/7 humidity with, or without a storm. Best thing you can do is trim the affected areas as they appear. If you leave it on, it will spread. Many times I have found no outer sign but when you peel a cola open, its running inside everywhere. Sometimes you have to make the choice to harvest everything or just trim. Bud rot is very quick and can seemingly appear out of nowhere.
P.S. there is a product selling in the UK called "BUD ROT STOP". They swear it stops bud rot and revitalizes the affected areas back to full strength. I have no idea whether it works or not, but so far I have not seen this in the USA. Hope this helps.
