Getting lower EC runoff Coco

[herojuana.tom]

The table is used as a mapping against runoff. With drain to waste you need to measure the runoff ec and ph; you have a reservoir that is isolated so it should remain fairly stable. The runoff EC was reported as having become lowered after passing through your rootzone which is a sign that the plants are uptaking the nutrients. As you do not recycle your nutes you would not be able to assess their water usage without closely monitoring your water runoff vs input volume. Would it be possible to get the runoff pH value so that we can propagate a second value onto the table… We see the runoff EC is dropping but what about the pH? With the runoff pH and EC plugged into the table we might get a clearer insight towards resolving any issue
