Help to buy an equivalent fertilizer from the farm shop

Isn't epsom salt very high in both mag and sulfur? My bag says 9.8% mag and 12.3% sulfur. How much should be used per gallon of water?

Epsom Salt is magnesium sulfate so yes it's high in both.

If I don't have a precision scale at home, which spoon can I measure how many grams?

A teaspoon (5ml) of Epsom weighs just under 5g

A teaspoon (5ml) of Epsom weighs just under 5g

So a teaspoon in 5 gallons of water. Thanks. That covers the mag and sulfur. But what about the calcium?

Is 2% calcium enough? Dyna Gro Grow has 2% in it already. Wondering if it would need more or that's good where it is.
