sorry if I sound dumb , just don't know much about fertilizer. I do know the smaller plants will take less than the big ones, ( I guess)

Then you need to go to our WiKi and read about fertilizer.
Info:Fertilizer - Bananas Wiki
Bananas need about 1 lb of nitrogen and 1.5 lbs of potassium per year (aka: growing season) ... So using NPK of 13-13-13, you would need give 7.5 to 8 lbs of 13-13-13 for 1 lb of nitrogen and 1 lb of potassium. ... You then need to supplement 1/2 lb of potassium with MOP (0-0-50) or SOP (0-0-60). 1/2 lb /.5 = 1 lb of MOP or a little less of the SOP.
Divide this weight by the number of feeding you plan on giving the plant during the growing season. Some members here give the plants extra ....
The math is easy. It was the unknowns of your question that made the answer difficult.
