In my case leaf issues are the result of over fertilizing the plant. I'm in northwest, Florida and our season is cut off by winter freeze at some point so I have to push the plant to grow to get bananas. I cut off the fertilizer until the plant corrects itself over the coming month when signs develop. This can also happen with too much water due to heavy rains but that corrects much quicker. Excess fertilizer and over watering issues are self correcting when the problem is identified.

Banana plants are pretty tough so don't sweat it!
