PPM/EC is definitely peaking higher after a few days than I normally allow. Plants seem happy for the most part, so I'm continuing to let it drift upwards. Today's res change was due to a 2.55k ppm in the reservoir and a 5.56 pH. Rather than topping off, I figured it was due time for a reservoir change to carry through the final 2 weeks. Res ppm after change was ~1k PPM (water out of the tap is 325-400ppm).
