My dwarf namwah is pushing out deformed leaves, and things get worse as time goes by.
I don't live in a banana growing zone and i'm pretty scrupulous in adding bananas to my collection (and however i haven't added anything in last two years) so i'm going to exclude that this is due tp any any pest/virus.
This just leaves nutritional deficiencies.
I have bee using (sparingly, i admit) a 16-8-24 mix personally made using ammonium nitrate, superphospate, sulphate of potash in correct amounts. My plant grow a a slight alkaline soil (i'm assuming 7,5 ph, surely less than 8, but it reacts with acids, so i guess there's some carbonate there).
What i should do? Last week i treated with 20 gr (0,7 ounces) of a complete microelements fertilizer but so far no improvements. Should i wait more? What do you guys think?
Of course i did take a couple of pics of my plant to help troubleshooting.
Keep in mind that on higher leaves you don't see wind damage, that's how they emerged from pseudostem.

Quality of the pic isn't excellent of people need something better i'm gonna take new pics.
Also, pup leaves are normal: so i think the element i'm lacking is pretty mobile in the plant.
