Yeah, i'd say try more oscillating fans/better airflow as that will help, tho obviously only if the mould is mainly related to poor airflow. Do u also run ur desk fans at night too? At night the plants are respiring & leaking major moisture. Airflow needs to circulate day & night and regularly air out the room the tents in too, if u don't already. But if ur humidity problems are due to local climate then u may need to buy dehumidifier.
Also, one thing about mould (which i must admit this is from reading, not experience thankfully!) is that alot of moulds will start growing from inside the buds, so by the time u see it on outside its already too late to save that bud. And thus i would say be careful with chopping some bits off & thinking other bits are still safe - do check before drying & smoking as it can be potentially dangerous dude.
