Please note that my regiment will piss off most, but it is effective and will end any battle and whatever is flowering currently is done as far as any medicine. That said if you would like to save every plant going forward I do have a solid plan, have used it and have no issues playing it forward.
You only need one product and that is Forbid 4F. It is systemic and it is not safe to smoke in NO WAY SHAPE OR FORM. Lets be clear here, we are saving these plant and have ZERO intention of flowering these plants.
What we are going to do is cut these back. Spray them three times over the course of 12 days and reveg them. Once we have nice green branches growing back, we will take cuts and flower those.
Sound like fun? Not at all to most but as a collector sometimes you have to do what you need to and this will eradicate the spider mite.
Unless something has changed recently, Forbid 4f is the only miticide that kills both live and the eggs on contact. There is nothing organic about this product but it works. About 90% of everything else out there will have you spending money for months.
I can describe this all in more detail if this is of interest, but the wife is here too take my ass to dinner, so BBL.
