That is true for large scale cost conscience banana plantations. But for banana hobby growers the price of the 50 lb bag and what is readily available for use is more the controlling factor. The extra elements are not used by the plant. Thus not a big expenditure loss for us as it would be for a larger banana plantation. ... So the 2-1-4 ratio is nothing special but simply the economical sweet spot of very large orders of fertilizer for banana plantations.
I use 10-10-10 ($15 for 50 lb) and supplement potassium with Sulfate of Potash (SOP) or Murate of Potash (MOP) applied to the ground in the spring. Later in the season I start foliar spraying a custom mix of nitrogen & potassium. These are easily obtained locally at an economical cost
