I mix 2tsp. ES per gallon H2O , every watering, along with Fox Farm Grow Big for the Vegging plant and Fox Farm Open Sesame for the flowering. I have not had any problems, but then our water is from a well , different water will make a difference. I bet you could put 1/2 tsp. per Gal.H2O with no problems. Do it for a while and see.Hi I found out my plants had Mag Def, and the cure is to add a epson salt.
I am wondering how often do I have to add epson salt to my water? Is it at every feeding?
