Since your purpose is to grow only in pots if I understand correctly, you don't necessarily need any special mix for your particular area (I assume hot and dry is the concern?). It would depend more on what you wish to grow and what is readily and inexpensively available. I don't think I would be trying to make bone meal (or blood meal) myself, I'm thinking the temperature wouldn't be high enough. I assume that would be trying to cover nitrogen and phosphorous requirments?

Peat moss can vary in its acidity, not all are very acid. Canadian peat moss would typically be acidic and you may not need sulfur to lower the pH further with that, or is it included to supply sulfur as a nutrient?
