I have a question watering coco. When were looking at ec or ppm obviously the feed charts are worried about whats going in but when a company says i need to maintain say a 2.0ec are we talking about maintaining that 2.0ec in the substrate itself or in the watering solution only. My substrate ec after a watering will be at 1.85ec by the next day its down to 0.3-0.5ec in the substrate. I thought the ec should go up as the media drys and not the opposite. Im lost at this point.
