Re: Musella lasiocarpa need some help
Looks like typical RSM (or similar) damage to me. Lasciocarpa seems very prone to it, much more so than my other bananas. Misting with water 3 times a day helps. However for the more stubborn problems, create a 50/50 mix of cooking oil and washing up liquid, put 15 m/l of this mixture into 1 litre of water and mix thoroughly. Spray the foliage with this paying attention to the underside of the leaves. Repeat twice a day. Keep the plants warm and ideally under light for 12 hours. That will kill off any beasties and allow the plants to recover.
