Well, one of the six is dieing. Every morning now the PH is up into the 7's and I still don't see any roots. I believe I'm going to change the water today. Should I add some of the Liquid Grow (7-9-5) maybe and half strength? They seem to be kind of stalled in just the distilled water. I want to find some of that CalMag+ as well, but haven't found it locally yet. Would that be in a gardening center or is that more of an item for hydro only?
