I don't know about the humidity but my neighbors have a banana plant that growing now just fine.
There is not realy rain now.
Before the problem showed up I watered each plant 20-30 liters (5-8 gallons) twice a week.
but since they don't grow I cut the watering in half.
I see no point giving a lot of water for plants that do not grow.
