My second time growing and now I think I have mites. Clones are about 2 months old and have never looked real healthy. The leaves have looked a little yellow spotted, and dull looking now I think there are tiny white bugs on the underside of the leaves. So much info out there not sure what to do. Can I use Safer end all spray? These plants are young and not to hearty. Could this be something else. Did we get these this way, or can they develope this somehow. They have been inside since we purchased them. Does it take awhile for spider mites to infest plants? Any info would be great.
