Why is there potassium in Silica Blast? Will the potassium in Silica Blast be a problem if I apply Silica Blast during bloom?

Silica Blast contains potassium because the source of silicate used in the formula is potassium silicate, which is one of the few plant-available sources of silica for plant nutrition. The potassium provided by Silica Blast will not cause any nutrient problems during bloom, due to Silica Blast’s relatively low applications rates (and subsequently low contribution of potassium to the nutrient solution).
