I grew some BB in my first crop and it turned out great despite my best efforts to kill it.
Seems like a hearty strain thats fairly easy going, those 2 plants were my best of the bunch. Have another fem seedling of it started a couple weeks ago, looking forward to running it and the skywalker og together again.
But yeah, bring that humidity down to around 50% as they start flowering and down lower to around 40% as they start to really push buds. If you cant go that low, just do what you can to get it down some from 50% and make sure they get good airflow around them.
