If you don't use neem or Mighty Wash.. you either have a rare species of Mite that has literally fk'd your grow room.. or you simply are not doing it right. It is easy to ask, whine, worry, about mites.. but the hardest part seems for people to actually bring themselves to the damn plant and take care of it. Don't worry kids, they are not crabs & will not contaminate your privates.. .if two of your fingers are too lazy to squish them leaf by leaf.. than spend some money on Neem oil or Mighty Wash. Before I think your mites have become immune to such methods.. I will lean towards you failing in your efforts.
Remember, if your grow room is not 100% legit, sealed, using co2, best lights& hoods.. YOU SHOULD NOT EXPECT TO BE 100% MITE FREE, Especially if you already have them.. THE BEST YOU CAN DO IS MINIMIZE THEIR EFFORS OF EATING YOUR PLANTS. Being Realistic, If you see signs of mites, (dots on leaves, if worse.. they will be on the tops of leaves creating webs.) Spray them & wipe them off, twice a week for two weeks.. After that, stay up to date w/ your cleaning.. Anyone who sees webs forming on the buds deserves it because they are neglecting the plant to begin with.. =/
Symptoms of mites IME. >>> Under the leaf you will see a single black dot(mite) or very few white balls(eggs)... 2nd symptom you will notice tiny white speckles on the fan leaves, turn the leaf over & you will see the mites + white eggs..
if you miss thoes symptoms you will then see Black dots(mites) on the top of the fan leaf, moving about.. laying webbing which you will see soon after. If you allow that to happen the mites eventually move onto the buds&nugs. You will see them when checking trichs & shit..
So my adivce if you Have Mites Like I Do... Simply keep track of them & take care of your plants.. the mites only get outta hand if you wanna be lazy & let your garden grow solo..
