EC Level not changing?
Hey does anyone know why my EC level hasn't really changed in a week? I had my 2 gal solution at 2.4 but it's only about 2.3 right now. Shouldn't my tomato plant have taken a lot of the nutrients out and therfore lowered the EC reading or is what the meter reading salt/used up nutrient? Should I just leave it alone until I get a lower reading?
I'm using a new bluelab truncheon meter which is supposed to not need calibrating and has been highly recommended.
