Stock Solution Concentrate
| Stock Solution | Preparation Instructions |
|---|---|
| 500 g per final gallon | Dissolve 500 grams (1.1 lb) of Boca Hydro Magnesium Nitrate in water, then add enough water to make 1 final gallon of stock solution. |
| Dry Product | Equivalent Stock Concentrate |
|---|---|
| 0.5 gram | About 3/4 teaspoon |
| 1 gram | About 1.5 teaspoons |
| 2 grams | About 1 tablespoon |
| 3 grams | About 1.5 tablespoons |
| 4 grams | About 2 tablespoons |
| 5 grams | About 2.5 tablespoons |
Dry-product reference: approximately 1 teaspoon dry Magnesium Nitrate = 4 grams, and 1 tablespoon dry Magnesium Nitrate = 13 grams. A digital scale is recommended for accurate dry dosing.
Hydroponics
| Target Magnesium | Dry Product per Gallon | 500 g/gal Concentrate per Gallon | Approximate Nitrogen Supplied |
|---|---|---|---|
| 25 ppm Mg | 1 gram | 1.5 teaspoons | 29 ppm N |
| 50 ppm Mg | 1.9 grams | 1 tablespoon | 55 ppm N |
| 75 ppm Mg | 2.85 grams | 1.5 tablespoons | 83 ppm N |
Hydroponic reference: One gram per gallon supplies approximately 26 ppm magnesium and 29 ppm nitrate nitrogen. Account for the nitrogen supplied when combining with Calcium Nitrate, Potassium Nitrate, or other nitrogen fertilizers.
Foliar Application

Compatibility
Magnesium Nitrate may be combined with Calcium Nitrate and Potassium Nitrate in properly prepared dry blends or concentrated stock solutions. Unlike Magnesium Sulfate, it does not introduce sulfate that can react with concentrated calcium and form insoluble calcium sulfate. Always perform a small compatibility test when combining with phosphates, sulfates, pesticides, complete fertilizer blends, or unfamiliar water sources.
