Hello, I had this problem in a little part of some plants before but wasn't a real problem until now that my 2 biggest girls are fucked up completely, they have every branch infected. They're two weeks into 12/12 and idk if there is anything to do or I should just cut them before it spreads to the other 3 that are right next to them but don't have any symptom. Please help!

I've had a lot of success with using this against Hemp Russet Mites. Have you correctly identified what kind of mites you have? I would hit them with some kind of spray that is organic based and won't leave you with many, if any residuals since you are still so early in flower. I wouldn't go past week 3 spraying stuff like that though. After that you could use a spray of diluted 91% isopropyl alcohol since it will dry out and kill mites but evaporate off your plants and not leave anything on the plants. You could and should also order some predator mites to put on your plants to pick off survivors and make sure they don't come back.

Thanks for the advices, I don't know exactly what kind of micro-mites are but they're doing lots of damage every new pistil dries out, calixes don't develop and resin never appear. I'll use the alcohol cause it's easier to find and I'm investigating how to acquire predators.

Is new growth looking like it has red dust or fungus accumulating or is there nothing like that aside from what you've described?

If red like I just described it would be hemp russet mites. From your description though it sounds like Broad Mites.

I second who dat is. Sounds like what I saw recently when the Broad Mites moved in....

First sign of Russets is a Taco'ing affect of the leaves! Russets suck juice from the plant and their saliva is toxic!
I've talked to many many experts on these and Broad mites!
By the time you see a problem... they are serious problem!!
I thought some of my plants were showing heat stress.. August in a greenhouse can do that.. taco'ing leaves.. I pulled a few a looked under a 100X mag and those little torpedo shaped bastards were all over the place!
Green Cleaner works, heat treatments work, predator mites work!
But what I learned is that they are always there in some numbers.. give them a desired environment and they can explode on you!
Be proactive!
When I transplant and place anywhere I order Andersoni predators! I spray my plants with Nukem or Green Cleaner... wait a week and hang the predator sashe on every plant!

Thank you very much guys, yes I think that this are broad mites, I had plants successfully harvested despite having a branch or two affected but this time is too much.
at first looks like heat stress too, it's what I thought the first time it happened for the dry looking and curled leaves specially the new ones, but now I searched for the real reason, took an affected leaf and looked carefully, and there they were some tiny destructive bastards moving around.
