This is some funny shit!
I almost feel it's really funny to read about fighting the problem for months and months......."I used this" and "I used that" and "nothing worked". Not to mention that ever present, "Well I used what you said before and it hurt my plants and did not work"......The next step is someone actually giving an answer that works because when they used what actually works, IT WORKED!
Most of those who fight mites for extended periods of time.....Must be dumb enough to not understand that their IN the rest of the grow......You find them, you treat for them (swallow hard, sigh that you have to go "non-organic" and USE the "big gun" treatment)!! Now you TREAT the GROW!
Bleach sanitizing solution and spray on every surface in the grow.....Walls, floor, ceiling, tables, chairs, nutrient bottles, empty pots and for gods sake, be sure that you use a "contact killer" and spray the surface of the soil/media at the same time you use that "big gun"!
"I used what you said and it burned my plant"......I doubt it! Unless you didn't READ AND FOLLOW the directions! MORE IS NOT BETTER!!!!!
What you say to use is a deadly poison! BS of the first order......don't generalize a usage label ! IF your considering a "big gun" mite insecticide and are concerned about it's toxicity.....GOOGLE
"product name" toxicology report and read it for yourself!
IF it is systemic,,,then read carefully about it's toxicity and it's toxic half life!
Any thing OTHER then systemic and you should be much more secure in feeling what your using is far safer then the "systemic"!!
Now then (don't look Dobbs). You want to actually get rid of the problem?
These work! They are the "big guns". I like the first one, best!....Had to kill off a problem with 2 types of mites in a fair sized perpetual grow....
Forbid 4F
Avid
Floramite
You can get small affordable amounts on ebay....These 2 I know are selling the real full strength product I trust the most!

If it didn't work for you - You used it wrong or got "had" by a fake seller, so quit yer bitchin at the product! NEVER buy one that says half strength or "generic" version!
If your so organic that you can't fathom what I suggest...Don't start your temper tantrum about "poison" and what we all should be doing....Keep your organic "politics" in the organic forum thread...
Did you choose the fast way and the easy road and are getting Forbid?
Follow the directions!
LIGHT misting on the TOP of the leaves...EVERY PLANT IN THE WHOLE GROW!
Now use a "contact" killer and spray the surface of the soil/media.....EVERY PLANT AGAIN!
NOW spray down the whole grow - EVERY THING!!! (bleach sanitize)
Repeat the sanitize again 7 days later....
I got RID of the problem in one fell swoop this way - 10 days NO mites
The grow has stayed mite free for just under 5 years!
Stressed plants give off a pheromone that attracts mites! Keep your plants unstressed and greatly reduce the chance of mites!
Use a Si supplement and it helps the plant resist the mites.
Good luck
