I am currently running a strain the seems to feed at an extremely light EC. I am wondering....is it possible, with my ~140 ppm tap water to be effectively locking out nutrients simply based on my nutrients being at a low EC? I'm just figuring...if my mix is @ ~300ppm and I'm adding backing approximately 140 ppm, that's a lot of starting ppm when you take into consideration the nutrient strength. Any help is much appreciated.
