Spidermites during 9th week of flower

As title says, I am in my 9th week of flower and I have seen so many spidermites. They are building webs on the leaves so far, hopefully I can kill them by the time they can mess with my bud. But how do I go about killing them without harming the plant and bud.

Yes I do my research, but all I ever see is "use organic pesticides," but I do not know what kind because the organic hippies never specify. They only yell "Use organic pesticides". Seriously.

I have tried using the Hotshot pest strip, but I had a bad reaction to it when I open my tent, my eyes get watery and I get a headache so I ditched it. Never had it in long enough to see results.

I wish I can show a picture of the level of infestation, but I do have buds that are about 2 bic lighters wide. And right now it seems they only chow at the leaves causing a lot of tiny spotting. They are specifically mostly under the leaves.

Please inform me on these "organic pesticides" which i'm assuming is friendly during a late flower stage. Thanks!

You have a fight on your hands. Try a 10% solution of isopropyl alcohol in pure water. Don't drench the buds too much and spray upwards to target the underside of the leaves.

not sure how long you plan to flower but at week 9 you're hit, its about management, not eradication. This is one way I saw a a grower do it successfully. He took each plant outside and aggressively squirted the plants top to bottom removing most of the webbing and the mites, the ones in the water were dead. not warm water though, cold water he found. he filled a tote with ice/water and dunked plants that were small enough completely under the water and shook them, really rustled them up after they were squirted/washed. a little dish soap wont hurt, like a drop, but be sue to rinse well. I watched his whole cycle this way and we enjoyed a pest free smoke when done. I figure if they ever visit here thats what I'll try. Then I saw another use a c02 tank and a large plastic bag. we could watch the things die eventually. he sucked the air out tight then cracked the tank and filled/tied it. his meter was inside but it topped at 10-12kppm I think. I'm guessing it was near 90 percent c02 in the bag for some time, but after about an hour there were no more moving bugs, including wigglers on the top soil in pots and some dead gnats in his little hydro stones. he rinsed them off with a hose when he was done and was cured, till next months clones came in of course...good luck, I hear mites suck

Sounds like a rough ass time for those plants! But, whatever works! I'd say spray them with mighty wash and see if it helps. Kills mites

Kill em off, drop the light cycle to 11/13 or 10/14 and the mites will start to slow down.

You can also bag your colas and mighty wash the plant, I have found that they hate this shit and don't even want to be near it.

Ok so I went back to that hotshot pest strip, but I have been only leaving it in during lights on. I just bear with the allergic reaction that I have with it, I quickly bag it a in ziplock bag before lights turn off. Also I noticed that the carbon filter, filters out the chemicals into, so I only have allergic reaction when I open the tent to take care of my flowers
