My ppm levels of my nutrient solution is 1100-1200 when feeding, Ph is 6.2, When I tested my ppm levels in my runoff with a blue lab truncheon meter, the light when to the highest level on the stick. It tops out at 1800. Is this bad news or acceptable levels ? Freaking out a bit now. Lol. Any advice would be awesome
