These are the handy dandy notebook charts I use to help me diagnose issues. This looks like more of a Mg def to me. I hate the term cal-mag. It has confused soo many new growers, even me for a while. The term implies that they are related or go together somehow, when they are completely separate and completely different. Their deficiencies are treated differently and show up differently. Hope the pics help!Can anyone help me here?View attachment 877252 View attachment 877253
