I think I may have some bud rot. See pics from day...

Hello ! I live in a 70% constant humidity level so next time you wanna know if their is a rot inside of a bud then search for yellowing leaves , generally if leaf is yellowing in the middle of a green bud then pull it and if it easily coming then open your bud to watch what's going one : this is how I discover my early undercover bud rot issues. I hope it will help you 😁👍

Based on what I'm looking at in your diary you look like your in good shape . Mould will be fluffy and grey sometimes white , a good way to check is to open your bud up and look at the inside usually you'll be able to see more fluffy mould . Bud rot is usually accompanied with sickly leaves and they just kinda happen for no reason you can also do this by opening the bud and looking at inside if it looks orange and dying you have the start of bud rot and my advice from there is to cut off that whole bud and look for further infected sites. You can combat both of these by simply controlling your humidity based on your diary I can see your humidity is at 53% I would lower it to 45 or even 40 the ensure that the risk of mould and bot rot is almost 0% . The lower your humidity in late flowering the better 0 risk of bud rot or mould and it also helps the plant pump out all those tasty oils we love ! I seen people go as low as 30 % with 0 problems ! I hope this information helps you on your quest ! -Happy Growing!

Really hard to tell. is in on every bud? do you have more purpeling=?or is it only the one. Because its blue Cheese there is apurpeling common. But try as Athos said to open one bud and if its more grey and got hairs and no good smell ..its budrot. Bud we cross fingers its just apurpeling. try to lower the humidity... better is Humidity around the 50 percent .

mmm... hard to tell. It looks like a purple / dark tinted bud. To be sure, I recommend that you try to break the bud a little, if it is bud rot you will notice inmediately, since it starts inside the bud an dit will come apart / break really easy
