You have the best autopot grow I have ever seen. Your pots look different from most of the ones I've seen before (larger). I am hand watering, but am also using liquid earth nutrients in coco, but have had problems getting the mix right. I was not using enough water and it concentrated in coco as it dried.

Did you go by the label on the bottles or have you modified? I am using a much weaker mix of nutes now and am still having problem. I would really like to know the exact mix per gallon you used during the different stages of your grow?
