You clearly know what you're doing, but I've never seen black or grey mycelium. You sure that mass of "good mycelium" isn't dead, a fruiting body, or a mold? Myc doesn't really lift above the substrate until its trying to fruit, and we wouldn't call the fruiting body myc.
Any chance at ID?
Also, damn, we really are in sync. I grew NLA last, WW now. Happily Minnesota organic grow!
