So far, I’ve just chopped off the infected portion. I have at least a few weeks before harvest and I’m trying to save all I can. Time will tell though. I’m heading down to my grow site with a leaf blower as soon as this rain stops.
I'm glad I cut it off completely like you said. I'm smoking the healthy portion of the cola above from where I cut it right now and it's a great high even though the buds on this plant are still pretty loose. The pistils haven't even drawn in yet. The rest of this is going to be awesome!
