I wintered over a potato plant, then tossed it when I noticed it had house mites. Next to it was my new sprouts, about 3/4" high, they too were contaminated. I sprayed them twice with “Green Cleaner”. Looks like the mites are gone but the plants has some pale tips and some funky looking rot on parts of the plant. The rot is so
tiny I can hardly see it with my magnifier but it’s there. Any suggestions?
