This is on the main cola of a plan I am planning on harvesting tomorrow morning. It looks like mold to me, but this is my first grow. Do I need to isolate her? Should I try to address the spot before or after I chop her down? It is on just this one tine spot as far as I can see. Any help or guidance is appreciated. I’ve read a fair amount about it, but not sure where to start.
