Fert Dosing

I'm currently dosing
NO3- 10ppm
K- 10ppm + 2
PO4- 3ppm
Ca- 30ppm
Mg- 10ppm
Tested parameters today, got bright red NO3 - 80-160 ppm, and dark blue PO4 10+ppm. I'm going to back off the NO3/Po4 for now. Question is, should I back off everything and half the micros as well? What should the next course of action be?

I would only reduce your nitrate and phosphate. With everything else available growth of your plants should start to drop NO3 and PO4level. That plus water changes should get them pack down to normal levels.

Ok @Surf, What about the Ca/Mg? Should I keep dosing the same? Wouldn't the water get too hard?
