Hi
@Bengrowerbr! I'm afraid you're having a fungus. Bad hygiene + continuous heat + poor airflow + high relative humidity can lead to this kind of issue. Looking at your temps and your relative humidity, it's more than likely a fungus/fungi attack. If this diagnosis is confirmed, at this stage there's not much you can do, but move the plant away from her sisters to prevent the invasion from spreading. Be very careful if you plan to smoke it, some bacterias can kill you, we've seen this earlier this year in california. Keep us up-to-date and good luck with this 👊
