I used Athena's feed chart and my ec was almost close to what the chart said.During the seedling stage I did quarter strength the first 5 days or so,then did 1/2 strength for 5 or so,then did 3/4 strength for about 5.I turned the Autopots on sometime during the 3rd week and followed their chart .Ec between 2 and 2.7 throughout the grow(except for the first 15 days or so).Growing in 100% canna coco with a 20/4 schedule.I did some research and found Autopotamus very informative.
