I am almost 1 year into my banana adddiction and have been dealing with similar problems for a while. After trying to figure it out on the web I had the soil tested and my soil was very high in everything but boron and nitrogen.
Started learning about the calcium boron relationship and had a big improvement when I added boron (and N).That was last summer, after much more rain than usual the last several weeks the symptoms returned. I put 10 grams of boron per plant and saw a noticeable difference in leaf posture within hours. That was over a week ago and I just added 10 more grams per plant to bring me closer to the 25 gram dose recommended in an article I read.They are looking even stronger now. I am aware of boron toxicity danger and could use advice on when to follow up with more. I have been using a well known fert. made for bananas and am starting to wonder if the fert. has what it claims. I wont mention the name until I am sure there is a problem. I have very hard water and before I started figuring this out last summer I noticed they were looking good if I was spraying the leaves more than once a day. They were getting alot of calcium in the spray.
Good luck
