Is anyone familiar with any natural predators or disease's associaated with this strain ? I have purchased a musella lasiocarpa and it has been doing great and then all of a sudden one of the leaves starts to show signs on the leaves I like to call sunburn. Naturally these sunburn spots begin to die off. So what I am looking at is a green leaf with a few brown spots. As the days progress, it continues to spread and get worse. When I first noticed them I cut back on the lights in terms of time and distance. Well after watching this plant tilt and the leaf continue to get worse I cut off the half dead leaf and I was looking at one one of the three remaining, which by the way look fine in color. I noticed on the top of the leaf on what I like to call the stem of the leaf little spots that at first glance look like water blisters. Looking at them closer with some magnification, I do not notice anything strange. Is this possible signs of some kind of natural bug or worm infestation that could of came with it and is just now showing ? I just need to know so I can fix it before it kills my entire plant. Even though this variety does not produce edible fruit, I am still trying to keep from losing it. I look forward to hearing any reply that could be of some help on this matter.

The first thing that comes to mind is overwatering. There are alot of diseases that effect bananas with M.acuminata parentage, but M.balbisiana, and other hardy wild ones are less suseptable to them.
I really don't know but you may want to take pics and post on bananas.org.
