I got spider mites on my plants. 3-4 weeks till harvest. There isn't many. A leaf here or there. I have removed the leaves and defoiliate the bottom useless leaves as well. Exhaust fan is always running and a fan blowing over the top and from the bottom. Also spray the bottom of the leaves with water. Seems to be working but I was wondering if there is a repellent I can use while the plants are flowering. I really don't want to lose these. They're gorilla blue. Any help would be awesome! Thanks
