Re: Black sigatoka or something else?
It's not Sigatoka, and even if it was, there would be no reason to kill the plant, it's not that kind of disease which needs such drastic treatment.
If the first photo is of the one which just flowered, depending on how long the bloom has been growing, that is fairly normal as the leaves will continue to age without being replaced, and eventually start to senesce anyway. It could just be exacerbated by the storm. The other photos don't really seem to show anything to be concerned about, again could just be from getting tossed around a bit, slight changes in season even if subtle, or some other mystery issue which to me looks like nothing serious.
