I could tell you how to make it but it involves a lot of algebra. The individual components can be bought at a reasonable price here:
But, you should worry more about macro (Ca, S, Mg) and minor (Fe, Mn, Zn, Cu, Mo) elements than the exact N-P-K. When you consider the work that it takes to add macro and minor elements, you are better off buying a complete mix such as this one:
I have used an older version of this (the formula has changed) for years with excellent results.
Another fertilizer that is very good is this:
Peters Excel 15-5-15 Cal-Mag Fertilizer, 25# Bag - Water Soluble Fertilizers | Greenhouse Megastore
My cannas. which are musa relatives, have grown better with this fertilizer than any other fertilizer that I have tried.
Usually the price per pound of fertilizer goes way up for smaller quantities but a small quantity of this fertilizer is relatively cheap:
Dyna Gro Foliage Pro 9-3-6 8oz Fertilizer Plant Food Nutrients | eBay
Again, this is a very good fertilizer with complete macro and minor elements but larger quantities have a higher price per pound than the other aforementioned fertilizers.
