Hydroponics DWC temp 80 Humidity 55 Ph 5.8 PPM 800 Using Tap Water that comes out at 150ppm general hydroponics nutes.

Recently lowered ppm to 800 to try to fix this issue. It was at 1200.

Potassium deficiency. Not burn. But your present PPM should still be adequate. Is the pH stable? Roots white?

The roots are crystal clear, white.

Are you measuring PPM and pH plus the solution level daily?
