Both of those are very high in Sulfur which can make your soil very acidic and fry your plants. Assuming that your sulfates are rated 20% available Sulfur, I would use:

per mature Musa or Fruit Tree in the ground. In a pot I'd use one-fourth of that or less.

If you don't have an electronic scale you can get one for about $15 from a kitchen store, like this one:
