Watch yer eye. Runaway eye pokers in there. Let's see, what I do to them... gave them some calmag, and npk. Idk how much. I put in enough to make it about 450 ppm. Looks like they're growing buds mm hmm. Oh some great white too. Im predicting next week they'll be a little bit bigger.
I tried dwc once OMG too much work to get them prefect roots.
I do mostly coco now amended with perlite and some organics down the road cause im lazy with pH-ing. :D
