Spidermites on Harvest day

I found spider mites on my one plant about 2 weeks before harvest. Moved it away from my other plant, sparyed the crap out of it with Capt. Jacks dead bug. Sprayed it again the following week because I til saw some small webbing occurring. Chopped the plant this morning and gave them a three bucket wash. 1st bucket had 1 cup of peroxide, 2nd bucket had 1cup of baking soda and 1 cup of lemon juice, and the the third bucket was plain water. Hope I got them all. Fingers crossed.
