I have rust spots sporadically around my plant. I have upped my calmag dramatically and I’m not sure it has completely stopped the issue. Any ideas?

Looks a calcium issue, how much dramatically over the recommended dose?

Is that per gallon? Wow way way too much , how does your Rez look is it still clear or is there precipitation because I had this issue before maybe not exactly like yours but after I seen my nutrient precipitated out calcium it was hard to get the plant to take it back in , maybe it's because it's not a mobile element in the plant takes much longer to correct
 
Check your roots if you can as a serious calcium problem leaves black tips on the root tips and next stage is brittle stems.
