Hi there, I live in Lisbon, Portugal, on my open balcony I grow dwarf musa tropicana (at least pricetag told so), it's 3 months old, you can see general look of plant on one of the pics. Grows pretty fast, has 7 new leaves! (when I bought it it was in pretty sad shape, only 3 leaves and all dry with blackish marks, removed them afterwards).
What happens is that new leaves after two weeks start getting patches of tiny yellow dots which after another two weeks develop into necrotic patches.
No insects / spiders spotted, I am sure of that.
Any ideias what it might be and how I can save it?
