I have a couple of potted plants going. One has a sprout that seems to be going strong, the other has a sprout that is barely popping out of the soil but is covered in what I believe are spider mites. You can only see them with a microscope and they are crawling all over it. I'm afraid to use any kind of insecticide being at this early stage. Should I just wait and see if it survives, or just throw it out?
