Mostly to keep overall ppm down, there’s already 300ppm of just calcium in the water here, plus whats in the H&G soil nutes…. I felt I could take a risk and switch to pure magnesium. If they show signs of needing more calcium somehow I’ll go back to calmag.
apologies for late reply, had a couple power outages here that lasted nearly an entire day.
after the first power outage and way too much dark time with no water:
another update later when I can reset the timers…
