Ethos Apex R-1 in Autopots

I'm loving the autopots. I did have a flood due to one of the valves not being installed correctly. Make very sure they are completely pushed down into where the little arms rest. Cleaning up the flood wasn't a big deal. I bought another set of autopots for my second tent. Some yellowing of the leaves on one and the start of nutrient burn on two. I realized I was feeding way too hot - the feed chart I'm using is "custom" but it's practically the same as the full strength GH chart. I dropped the PPM from 720 to 450 by just adding RO water. Plants have already recovered. Using the scrog net is easy and it's filling out well.
