No, not yet. Expanded the coco with full strength Jacks, then first couple waterings was just RO water as I figured there are plenty of nutes in the coco. After 2 waterings with RO, I did a watering with Jacks, then another RO water only just yesterday. I don’t feel daily watering/feeding is required just yet, but getting close as they do need to be watered every other day now and all future waterings will be with full strength Jacks.
It’s going to be hard for me to get past the mindset of “Don’t water if it’s still wet” but I’m not letting the coco dry out anywhere near as much as if I was in potting soil, but I’m not keeping it saturated either.
