sounds like you may have caused the leaves to burn by spraying soap on them every day for a week. the waxy cuticle is only so thick and once removed the plants have no protection from the light. homemade concoctions may be cheaper than store bought products but store bought come with directions for use and quality control. Eutrophication by the way is a term used when excess runoff creates Algae blooms in ponds. over fertilization is what we say in the Hort industry and i assume you are asking about. if you do have mites, check out the thread "no more spider mites on cannabis"
nicpett Reviewed by nicpett on . Eutrophication, nutrient deficiency or spider mites? We decided in June that it could be fun to try to grow some weed. So we got on the net and bought a feminized seed. We planted it in it's definitive pot, as advised by the seed seller. We planted it in a 16" pot, filled with a mix of store bought black earth, potting mix and sheep compost. It's been now about 5 to 6 weeks and the plant is almost 2' high. Unfortunately, about a week ago, we started to see some tiny whitish discolored spots on the leaves, especially the ones at the base. Rating: 5
