How much K2SO4 to add in EI for Potassium Deficiency?
The plants in one of my tanks, a 75 gallon, which I've kept with great success up to now, seem to be suffering from a Potassium deficiency, which would make sense as the plant density has increased and I haven't been adding an extra source of K. Up to now I've added 3/4 teaspoon Potassium Nitrate and 1/4 Mono Potassium Phosphate every other day, Seachem Flourish 7.5 ml on the other days. How much Potassium Sulfate should I add? I read somewhere on the forum that I should be adding 1/4 teaspoon together with the Potassium Nitrate and Mono Potassium Phosphate.
