I have fox farms calmag. My tap water is only about 90ppm so not much in it.Ok I kind of thought it might be. Thats the 1st sign of a calcium deficiency creeping in, and it could very well be your recurring issue. Do you use any forms of CalMag or dolomite water? And not to worry, your refractometer will tell you for certain and then you can decide what comes next.
