The higher EC wasn’t exactly a plan from the beginning, it just happened to work out that way. I’m following the feed chart for the dual fuel line for the Autopots, but I’ve also added calmag and silica, so that’s where the higher EC comes from. If you go by the feed chart alone, I should be somewhere around 1.6 mS (1600 μS) right now, but I’m actually closer to 2.1 mS (2100 μS). I was just noticing that they weren’t suffering any nute burn, and that maybe it was because there’s less opportunity for the EC to raise in the pots between fertigations (watering with nutrients).
