Is my math right - adding Equlibrium, Limestone, MgSo4? - Fertilizing

I'm using RO/DI water. Based on Fertiliator, I need the following amount to get my 100 gallon tank within ideal parameter:

4 teaspoon of Equilibrium
4 teaspoon of Calcium Carbonate or Limestone
2 teaspoon of Magnesium Sulfate

This will give me about 10ppm of K, 9ppm of Calcium, and 4ppm of Magnesium. This will bring my GH to around 4 degrees and my KH to around 2 degrees.

Is this right? Can someone verify? I've read most people only add 1 teaspoon of Equilibrium to 50 gallon of water.
