Robertsanswered grow question 3 years ago Growing In coco, and what your saying tells me your approach in coco is wrong. I grow in coco. It required heavy irrigation. Plus constant ph monitoring of run off. Every other day I put a minimum of a gallon, and a half through my 3 gallon fabric potters. You can not overwater in coco. You can flush coco every day, and supply with fresh nutrients, and it will be fine should thrive even. Coco Is hydro in a potter or bag. So constant ph water is needed, and this will stop your ec from ever getting too high again. Coco stays 90 to 100 percent saturated. No dry time.
