Bananas will only utilize about 1.5 times as much Potash as Nitrogen, and about 1/16 as much Phosphate as Nitrogen. On a yearly basis, they can utilize about 1 net pound of Nitrogen from available sources.
You are feeding them 1.5 times as much Phosphate (P) as Nitrogen, and about 4 times as much Potash (K) as Nitrogen. So, you are wasting P and K. On the other hand, at the given dosage you are probably not exceeding maximums. If you do so, excessive Potash will limit the uptake of other nutrients, particularly Sodium, Iron, and Manganese.
