If there is no magnesium sulfate at all in your nutrient formula then add 1 ounces (by weight) ie 28 grams, per every 5 gallons of mixed nutrient water. That would be the equivalent to using a GH formula of Florabloom as Part B of a two Part formula. There is no magnesium Sulfate in their Part A Flora series. That will provide 150 ppm of magnesium.

Further proof, the fat man rocks.

This is the first time I've read a post from him. I was just impressed with what he had to say. Pity he's banned. Nice impressionist CO flag icon btw.

Hey all,

I am just wondering, for those of you out there that use epsom salt (magnesium sulfate) during flower, how much do you use per gallon?

Thanks.

I shoot for 50ppm per gallon on the tds meter. What are you using it for?
I use it to get 7ppm of elemental sulfur per gallon, the Mg is a non-issue for me.

I suggest you take about a pound of MgSO4 (500g by weight is a good start) and dissolve it in a gallon of water to make a stock solution, decide what your target MgSO4 ppm is and why, then take some measurements and go from there. It depends what you have going on already. I use MgSO4 from week 2 to week 7, only for the sulfur, because otherwise I don’t have much S in my solution at all. Media, water source and fertilizers you are already using are important factors in this decision.
Do you have a TDS meter? What country did you buy it in? (Seriously) Are you in soil? What are your water source parameters? Fertigation plan? It all matters.

this was a 2009 thread until it was recently revived from the dead. FYI.
