I’ve had basically undetectable NO3 and PO4 and have raised my NO3 to 3ppm over the course of two weeks and PO4 to .02. Was curious as to how long it takes acros usually respond in getting more of their color back from a lighter shade, in response to the addition of the nutrients they are now supplied with.
