Are you using RO water? If you are using tap water, it is probably the Cal-Mag causing the problem. Tap water has plenty of calcium in it, usually too much. This will cause lock outs of mg, etc. This is what it looks like is happening. At least to me.

Also, I'd bring your pH down just a bit. On my drip system, with the GH Flora series nutes, I run mine at like 5.4-5.8. I think the combo of the pH plus the excess of calcium from using the Cal-Mag is what is causing your problem.
