Ghost2022answered grow question 10 months ago Hi mate, I had this last year. It spread to the buds too. I asked Seedman who I got the seeds from why it was happening. They said it's if cold air is getting to it somewhere. Not necessarily all the time but it has got to it. Don't worry too much about it. The buds came out a brilliant purple and it smoked really well! Hope this helps mate. Hope you get a fat harvest!
