Strange discoloration on Super Dwarf Cavendish
 

My plant has those strange discoloration on a part of the last leaf.
The plant is a (I identified it as such) super dwarf cavendish. It was sold along some other houseplants in a grocey store.
I own it since 2 years. I kept it in pot during last two winter and i planted recently in full sun, in the ground, in my vegetable garden.

I'm fearing a virus, but i really don't know what it may be. I have had an heavy aphid infestation this year, but no other plant of mine showed any sign of illness, ever, so far. And i saw aphids just rarely on bananas, and never actively feeding.
Suggestions?

Uhm, thank you. It may indeed be some kind of micro-nutrient deficency, i never fertilized my nanas this years, except with some nitrogen.

It could be very complicated to use fertilizers without an expert advice..........

I preffer organics.............

You can add Wood Ash for K............or Bone Meal for P and Ca..................for exemple.........

Looks like nothing serious to worry about. Perhaps a minor nutrient deficiency or just stress.
