Here's another cent tossed in....Blaze I'm one of the folks who answered your question about LK--since reading this post I have been watching my plants like a hawk and two quick notes: I still have that weird build up on my roots as we talked about in your post and have been noticing it for awhile (also present on the roots of my last grow) and my plants don't seem to--and never have seemed to--have a problem from it. There is no odd smell or anything coming from them. What does this wilt on the roots smell like?
