Red/bronze spots on older growth/ purple stems.

My plants are getting these spots on the older fan leaves. They start out as small red specks, then as they progress and multiply they turn necrotic. The stems on my plants are turning red as well, not just the petioles, but the center most veins of the leaves, and the steams on the nodal shoots are turning purple as well. Anybody know what this could be and how to fix it?

I was thinking calmag or could be an excess causing other issues

ive been using 5ml/CalMag per gallon. My system is about 30 gallons so I usually mix about 15 gallons of straight up nutrients then dilute with 15 gallons on RO to get the desired ppm. Does that sound about right?
