I'm sorry I totaly missed ur response, by last calculation I should have 0.306 mS/cm (150ppm)
I was going to say you can probably walk on water with a 3.06. That’s really not that hard. I’ve run water with a water company analysis of 145 but still had to add cal mag. Especially around weeks 4-5 in flower.
