@yeatster, I wasn't singling your mix out, more of a general observation from over time.
RE:cal/mag in your mix. Did you add any dolomite lime to the pro mix? I know it has some added, but it's a very small amount and can be insufficient. Takes care of pH and cal/mag issues. Best added to the mix when mixing, but can also be top dressed in.
