Potassium Sulphate

[SLIM]

Hi

can anybody tell me how many tsp of potassium sulphate i should add to 500ml of ironized water to achieve 5ppm? Going by 10ml per 100 litres?
OR to put it another way, how many tsp of potassium sulphate is 55g?

Thank you

To achieve 5Mg/L of K? 55.5grams, which is about 11 teaspoons.

If you are dosing potassium nitrate and monopotassium phosphate then you will have enough levels of potassium.
