Only Good 2 Use If U Are Lacking Magnesium Because It Also Boosts The Nutes Like NPK

Magnesium and sulfur are the two major components of Epsom Salt. Crop researchers have determined that magnesium is:

A critical mineral for seed germination.
Vital to the production of chlorophyll, which plants use to transform sunlight into food.
An aid in the absorption of phosphorus and nitrogen, two of the most important fertilizer components.

Sulfur, the other major component of Epsom Salt, is also an important plant nutrient. Sulfer may:

Contribute to chlorophyll production.
Make the primary nutrients (nitrogen, phosphorus and potassium) found in most fertilizers more effective.
Although magnesium and sulfur occur naturally in soil, they can be depleted by various conditions, including heavy agricultural use over time. But unlike most commercial fertilizers, which build up in the soil over time, Epsom Salt is not persistent so you can't overuse it. Tests by the National Gardening Association confirm - roses fertilized with Epsom Salt grow bushier and produce more flowers, while the compound makes pepper plants grow larger than those treated with commercial fertilizer alone.

Magnesium is a component of the chlorophyll molecule and serves as a cofactor in most enzymes.

Magnesium (Mg) deficiency.

Magnesium deficiency will exhibit a yellowing (which may turn brown) and interveinal chlorosis beginning in the older leaves. The older leaves will be the first to develop interveinal chlorosis. Starting at leaf margin or tip and progressing inward between the veins. Notice how the veins remain somewhat green though as can be seen in figure 15.

Notice how in Figure 16 and 17 the leaves curl upwards like they're praying? They're praying for Mg! The tips may also twist.

This can be quickly resolved by watering with 1 tablespoon Epsom salts/gallon of water. Until you can correct nutrient lockout, try foliar feeding. That way the plants get all the nitrogen and Mg they need. The plants can be foliar feed at ½ teaspoon/quart of Epsom salts (first powdered and dissolved in some hot water). When mixing up soil, use 2 teaspoon dolomite lime per gallon of soil.

If the starting water is above 200 ppm, that is pretty hard water, that will lock out mg with all of the calcium in the water. Either add a 1/4 teaspoon per gallon of epsom salts or lime (both will effectively reduce the lockout or invest into a reverse osmosis water filter.

Mg can get locked-up by too much Ca, Cl or ammonium nitrogen. Don't overdo Mg or you'll lock up other nutrients.
"I" personally, wouldn't/don't 'add' mg, unless a defficiency is detected or at least 'suspected'.
