Hey all- just canvassing a few threads that I've been in for a bit, to see what folks think this might be- deficiency? I picked up some dr repair micro nutes and mammoth p (iron), just in the advent it's a metals issue?? Select leaves only at this point. While i realize this clone is way overdue for transplanting (just taken care of that actually), i don't think that's the issue and not too worried, as i saw this on my last run on the same strain and wasn't a major issue.... it seems like some older growth has an almost iridescent dark blue color as a precursor...
