Correct. Keep in mind, when you go too high with the nutrients the roots begin to die and rot, dropping pH in the root zone like a stone in the ocean. MANY hydro growers believe they have pH stability problems from their pH up or down, or the buffers in their nutrient solution are "not enough." They're actually killing the roots and creating the pH issues with over-feeding. From what I've read posted, a lot of soil growers have the same issue going unresolved until they check run-off pH.To be honest I use the lowest EC possible and the plants seem to thrive.
Why increase the concentration when your plants are fine? You're asking for trouble doing that.
