To calculate ppm concentration in water, for example of Nitrogen:
[Total lbs] • [% N] • (1600 / 135) • (100 / Gallons) • (100 / IR) = [ppm N]
where
[Total lbs] = total pounds of fertilizer mix
[% N] = percentage of Nitrogen in the fertilizer mix
Gallons = gallons of water being used with the mix
IR = injection ratio. If you are not using a fertilizer injector, then IR = 1.
It appears you are only supplying your bananas with raw N-P-K. They would both perform better and taste better with a micronutrients supplement. An inexpensive way to do this is with Liquid Seaweed Extract. It is not balanced for plants, but is better than none.

The ppm-aspect is really interesting, never did it this way, I suppose also it is difficult for me to make according to ppm-ratio.
I have sprinkler-system, before feeding the plants with fert I water about fifteen minutes to prepare the plants and the soil,
then I give the fert in a 220 liter barrel, not at one time, giving some amount to the barrell mix it with water and do this a few times again.
This is because for better distrubuting the fert, also I do not want to burn the bananas, suppose urea can burn , when high ppm in water.
After giving fert I go on with watering for about 15 minutes, I check visually and sometimes I am digging the soil a little .
The micro-nutrients-aspect is a aspect that I have to care more about.
A few days ago I bought an american product called Rally, from the Nutri Phites series, produced by Biagro Western Sales INC., looks like a very good product for me.
I give it once a week now to the plants , the amount is 300 g evry use. Hope this is a good amount.
Nutri Phite Rally has 0,4% Bor ,1,5% Copper, 12% Iron ,3,5% Mangan, 4% Zinc, 2% Magnesium, and 14% S (sulfur).
I also give Humic Acid to the plants, about 1,5 liters every week, I could buy some canister with 20 liters for a very good price.
According to the company the product is usable for organic farming, the product itself is called organic.
The product is called Toromol, from a turkish companya called Makrotarim.
