Re: Yellowing and brown leaf spots
Without seeing more, I would guess fertilizer issues. Do you have a few more pics? Maybe the whole plant in one and a whole leaf with petiole going to stem also? Being in Russia, I doubt it's in the ground.
If you lose your head and give up, you neither live nor win.
Varieties I supposedly bought: Manzano, Cavendish, Blue Java, Sweetheart, and Gros Michel.
What it seems I actually have: Brazilian, Cavendish, Namwah, Dwarf Red, Gros Michel, Pisang Ceylon, Veinte Cohol and SH 3640, and American Goldfinger. FHIA 1, Paggi and FHIA 17... Always room for one more.
