I use a similar setup with coco/perlite, and have never once had an overwatering problem. There have been times when I was likely watering to >30% runoff multiple times per day. My automated top watering keeps the coco wet all the time. I hit it six times a day to runoff.

Well perlited coco is hard to overwater. Maybe not impossible, but really difficult, IMO. :pighug:

Yup they were definitely underwatered from not turning the timer on for the irrigation. They look better now leaves are still ugly but they have forsure perked up :woody::thanks:
