Tommy716answered grow question a year ago So from what I can see it does look like you have some mold going on. Yes, the branches and the sugar leaves will trap some moisture, but typically it's firm too high of humidity in your grow room. You can also happen if the plant is damaged and it has any open wounds. I've even seen it happen from people cutting their sugar leaves too far away and it ends up turning into a spot with mold. My two cents. Hope it helps
