i’m not a insect guy but i think your right,I notices little white spots on the leaves of one of my plants, so I put a fan leaf under the microscope. It was then that I saw little green bugs that look somewhat like spiders. I suspect they're spider mites. You can see one big one and a few smaller ones in the video.
What should I do?

Two-spotted spider mites: How to identify and treat them in your marijuana grow
Cannabis producers can stay ahead of two-spotted spider mites with solid scouting, preventive release of predatory mites and target sprays.mjbizdaily.com
It's an indoor grow. The crop is 27 days past the flip. The two plants have been healthy. One plant has a lot of mites and the other just a few.i’m not a insect guy but i think your right,
are you veg or flower?
how are the plants?
indoor or outdoor?
someone who knows bugs will chime in and help out..
It's good stuff to have on hand. I bought some 3% without a specific purpose. Now I'm glad I did.i always have around a gallon of 29% h2o2 to use for many things..
good to have at hand when needed..
i use it to clean stuff, kill mildew, germinate seeds.. etc..
3% just spray at that strength don’t add any water that’s why buy a stronger strength to mix to a strength needed for whatever your using it for.. tech grade is kinda better than food grade as it has a longer shelf life and the effect will last a bit longer when used..It's good stuff to have on hand.

I mixed the 3% H2O2 solution in a 1:1 ratio with tap water and sprayed the plants and tent with it yesterday. Today, 24 hours later, I cut off a leaf and put it under the microscope. There were still spider mites crawling on the leaf. There might have been fewer smaller mites, though. So, I sprayed the plants again. I also took the leaf I cut and sprayed it. I'll check it again in a few hours to see if the spray had an effect.
I understand a 9:1 water to alcohol solution is supposed to kill the pests, so I might try that, too. Maybe alternating solutions will help.
The diatomaceous earth is supposed to arrive tomorrow. We'll use that as soon as it arrives.
Thanks @GNick55!3% just spray at that strength don’t add any water that’s why buy a stronger strength to mix to a strength needed for whatever your using it for.. tech grade is kinda better than food grade as it has a longer shelf life and the effect will last a bit longer when used..
Treat 4/5 days in a row to get eggs and young ins - hard to get rid of completely until you can clean a sterilize everything ! Focus on control of population that’s my opinion - otherwise DW is correctThanks @GNick55!
I made a stronger mixture and tested it. It seems to have worked. I didn't see any mites moving around. I'll keep testing and spraying. I read that a female can lay 16 to 20 eggs per day and that the eggs can survive as long as four weeks, so I'll have to keep working this for a while. I'm glad it wasn't worse.
Thanks. I'm seeing that bad news everywhere I look. We cut off a lot of the plants. The hydrogen peroxide is working. I'm checking for them using a microscope. We're also using diatomaceous earth. My plan is to keep spraying and testing. So far, I think we are at least out ahead in this one.Hey Bigblonde ,i dont want to be the bearer of bad news ,,,,, but mites are a nightmare and a formidable opponent , i dont think hydrogen peroxide is gonna cut it ,i like to hit em with neem oil then go nuclear as i get more frustrated ,thats only if the plants are worth the energy ,in other cases ill just trash the grow and super clean up
Thanks. I've read about some of those. Azamax seems popular. We'll keep working on this.
We're talking it over. Another plan is to spray them well, put bags over them, chop them and hang them upside down while keeping them inside the bags. We don't want to spread the critters or their eggs to other areas of the house. Once the tent is empty, we'll be able to sterilize it so we can begin our next grow.I'd just put them outside away from the house and see what they will do.
I suspect those critters have already found their way throughout your house.We're talking it over.

Be careful with spraying Green Cleaner that far into flower. I believe they say on the instructions you can do it but it will effect the taste of the finished budI use green cleaner and a fog master jr. Best setup there is and have gotten rid of my pests when the pump sprayer wouldn’t. Highly recommend this combo
I had spider mites my last grow and thrips on a few. This handled them. And you can use it up until harvest.
Now I just use it weekly at a low dose and no issues. I use it up until week 6-7 of flower. The fog master jr also makes it so you save whatever you’re using. It’s very efficient. I’d go through way more using a lump sprayer and it didn’t work even 1/2 as good
