be careful when buying clones from a dispensary i bouhgt 8 clones from a dispensary i checked them out real good when i frist got them no bugs .i grew them for 4 weeks they were looking good . when i put them in the flower room a week later one had mites only one plant so far i have not seen any mites on any of the other plants yet but there must have been eggs on the one plant when i bought them an now they hatched WATCH OUT
Hate to break the news to you, but if you grew the plant for four weeks, and then you started flowering, and then you found the mites, the mites probably originated at your place, not the dispensary.
I had to just stop reading. Mites not on clones for 4 weeks into flowering then they get them def. your prob not dispensery
