Reduce the PPM to 600-700. You're running her too hot.

For an example. My highest ppm has been 750. I'm using RO water. My tap will add another 250ppm. Then another slight increase having to add so much PH down to adjust the tap water.

I've had to use tap for a few days. My ppm was a disaster. So know, when I suggested 600-700ppm. The starting water has a zero ppm.
