Alright. The stems turning brown from the fans you were referring to? I've never heard of that before. My feeling is fat buds, maybe a weak plant from stress and a lack of airflow may be the culprit. These are my thoughts for the morning.I had two fans but one died a few weeks ago. The rh has been below 50% for the last two weeks now. Never had bud rot before. It looks like the inner stems turned brown and the mold spread from there.
Many times my thoughts are meaningless, for the record.
