@Gr33nFi3ld, calmag has also Nitrogen in it and you don't want N and you also don't need Calcium. In order to raise Mg with calmag a lot of Nitrogen will be in the game. Epsom salt is pure magnesium sulfate just what you need ..cleaner than any calmag and also faster to act..and way cheaper. your choice
