Yeah it has Calcium and Magnesium in the fertilizer, does not affect Ph from my testings but increases GH when I dose it the right way. But I just did not know the reliability of that. Thanks guys
Are you certain? I just checked the ingredients, and there is not sufficient calcium to increase the GH, though if you have a digital GH meter or something it might detect minimal amounts. But the API GH/KH liquid test cannot as it only measures in degrees, and there is not sufficient calcium nd magnesium in Thrive to increase the GH by 1 whole degree. Maybe there is something else occurring?
