epsom salt and water mixture?

OK so in the growfaq section it says that you need to do a epsom salt and water mixture for a magnesium problem but it doesnt say how much epsom salt to a gallon of water,,, can someone please help me out a bit,, I am in a water medium,, 3 weeks in 12/12.

1-3tbs per gallon. cal/mag is a better solution.

Im sure there are better ways,,, but,,, unfortunately I have epsom salt now so Im hoping that it will do for now.....

if you are watering in soil use 1 tbs/gallon, but mix it with a cup of hot water so that it dissolves then add it to our res. For foiler spray use 1 tsp/gallon and spray away
