if your plants are magnesium deficient, yes. Otherwise, no. It's a good option for adding magnesium if your plants are particularly magnesium hungry, but otherwise not calcium deficient. If you have no deficiencies, I wouldn't add any

i recently switched to flora trio and did have mag deficiency in my veg plants specially, only the bloom has magnesium so i would advice a bit of epsom salt in veg

Welcome to GWE
Easy with the salts, if you dont need it you can cause toxicity. If you use tap water, you have plenty. (check with your water provider)

Smoky, I agree with that opinion, especially if One uses well water. If You are un sure, contact the local water company for a report on the contents of the water that they are providing You. If You are on a privet well, testing of the contents can be done by most testing laboratories.
