When I learned to grow I was taught to use calcium nitrate and Magnesium sulfate (Epsom salt) for cal/mag. I always just mix it in the water before I give them a drink 500ppm during veg and 250ppm during flower. Are there any other ways of getting the plants Calcium/Magnesium? The reason I ask is I heard the Epsom salt will build up the salt levels of the soil very quickly.
This is mostly for the sulfur content. Which brings out the terpenes. I use a teaspoon per gallon.
You can crush up egg shells and sit in vinegar for a few weeks, there’s your natural source of calcium there.
