I've only seen this discoloring in one spot. The plant looks generally kinda ratty, but I'm writing that off to it's stage in life. I'm looking kinda ratty myself. The bronze leaves don't pull out easily, so hopefully not the dreaded butt rot...I used a stainless steel toothpick to poke around and pull the bud out a little and it didn't seem nasty on the inside. I've had tons of WPM. (Girl scout cookie outdoor Virginia in grow bags about 55 days into flower) Any ideas? Thanks-
