Hi bsmith782,

Here in Seattle we have very soft water, typically 1.0 DH. There are times that my plants exhibit signs of Ca or Mg deficiency, when they do I dose CaCl or MgSO4 (Epsom Salts). Here is a link to a site I use to help me diagnose nutrient deficiency or excess symptoms. Scroll about 1/2 way over and 1/2 way down. Hope this helps! http://www.finostrom.com.gr/images/a...lizers/map.htm
