Should I add magnesium or not?

Hi,

I have been using gypsum, calcium chloride and lactic acid to control SO4/CI ratio and PH and been wondering if I should add epsom salt to meet the magnesium levels of the brunwater profiles I've been using.

My water has 1ppm of Mg.

Would this be beneficial at all for the mash and final beer or are the levels of magnesium from the grains enough?

I don't think it's worth it. You're going to get it from the malt anyway and it's the sulfates that are really important there.
