hey guys, i just took some cuttings from a friend and brought them home and put them in my cloner. upon further inspection i found some white and yellow spots about the size of the end of a pen. I inspected every leave, both top and bottom side for spider mites and i found none? i am baffled to what could be causing these spots, they have been in the cloner for a week and the spots have not gone away, but they dont look like they have gotten much worse... Could this be caused by a disease or something? thanks!
