Congrats that you harvested, fuck the weight, you grew your own smoke, legally? My first legal harvest I still was checking out windows and hoping no one came knocking on my door, that comes from previously doing it in a much less tolerable state illegally.
Mites, I've tried stuff that didn't work, stuff that kinda worked and I would say if you are not close to harvest use AZAMAX shit knocks em dead in 9 - 15 days (they recommend that you apply 3 times to get rid of mites applying every 3 days, I do every 5 days with same results, well I've only had to do it once and that is what I did). If you are a couple weeks from harvest use Mighty Wash, shit is very expensive so reserve it for that "oh shit I need to cut these in 2 weeks and be able to smoke them" scenario.
