Peanut putter pie mother

About a week and a half ago I noticed some weird brown spots forming on some of the leaves and it was driving me insane. I thought i was battling a bug I couldn't see. I pulled out a jewelers loupe and noticed this plant was finishing up and was coming to the end of its life. I started flushing Tuesday and will chop this coming Monday. The yield on this plant is going to suck. My guess is that ill be harvesting a little over an ounce. This might be my lightest harvest ever.
