Epsom salt is the household name. It's also known as magnesium sulfate which is a little more revealing.
Here's a copy, and paste from Wikipedia.
"In gardening and other agriculture, magnesium sulfate is used to correct a magnesium or sulfur deficiency in soil; magnesium is an essential element in the chlorophyll molecule, and sulfur is another important micronutrient. It is most commonly applied to potted plants, or to magnesium-hungry crops, such as potatoes, roses, tomatoes, lemon trees, carrots and peppers."
The JR Peters mix is low in both magnesium, and sulfur. So epsom salt is added to complete that mix. I use what's called the 3-2-1 formula. In a gallon of tap water I mix three parts 5-12-26 Hydroponic, two parts 15-0-0 Calcium Nitrate, and one part epsom salt. Mixing is pretty easy. I use measuring scoop spoons. For both 5-12-26 Hydroponic, and 15-0-0 Calcium Nitrate I use a 1/4 teaspoon scoop, and the epsom salt I use a 1/8 scoop. They mix easily with tap water. In fact the formula is made to use with tap water.
They have another formula for RO water if you wanna go that route. I've never tried it tho.
It might a bit confusing how I use the 1/4 teaspoon scoop for both 5-12-26 Hydroponic, and 15-0-0 Calcium Nitrate, because the ratio is supposed three parts 5-12-26 Hydroponic, and two parts 15-0-0 Calcium Nitrate, but by weight it's 100% correct. The 5-12-26 Hydroponic is heavy, and gritty, and the 15-0-0 Calcium Nitrate is light, and fluffy. (like powdered laundry soap)
