I am scheduled to harvest on or around Christmas. I walked in tonight to feed the girls and I noticed a huge cob web over one of the buds! I live in the desert, we don't have a lot of bad things floating around that can harm plants. My house is very clean. My grow room is extremely clean. Somehow something came in and cobwebbed one of the top colas. Have you heard of this? How do I fix it. How do I get rid of the web covering this huge bud group? Otherwise the plants look healthy, even the one with the web looks healthy. It is just odd.
