You can use a Organic Gem a liquid Fresh fish fertilizer (97% fresh fish 3% food grade phospuric acid, same thing that is in soda pop) It's not listed as a insecticide, but when you foliar feed with it the oil in it does help kill the spider mites and you will help feed your plant at the same time. I have used this stuff for over a year now on my vegt. garden and it has never been better. I noticed that there is finally an ad for it in the HT 420 mag. Hope this helps.:thumbsup:
