Broad/russet mite contam on some nearby plants. These aren't affected to the same extent but there is definitely spindly growth coming in. I've treated two nights in a row with insecticidal soap and neem oil, ordered predatory mites/ladybugs, need more advice on products/methods

Preventative maintenance is always your best offense against pests like this. Find a good product, like Smite or Mercenary, and foliar spray with it regularly to keep bugs away. I’ve been growing for a few years now and I’ve never had one issue with bugs and I believe it’s because I spray to prevent bugs so they aren’t a problem.

Hey there so spinosad spray will kill on contact. You can make an essential oil spray which is great for many bugs, eucalyptus lemon and rosemary are good diluted with water. You can spray the plant with water or give it a bath to help blast them off. Beneficial nematodes. Dont over fertilize as this will excite and attract the mites more. You can adjust the temp and ventilation as this will make them uncomfortable, i think they can flourish especially in the nice warm climate that the clones enjoy. Lastly if you try everything and it doesn't work, its ok to throw out plants and start over. I hope something works for you, pests can be so frustrating. I battled all summer with bugs being outdoors. ✌️ good luck with the hunt.

Hey there NullHypothesis! Spider mites love stagnant air and heat. They do not mate in windy conditions so typically setting up a fan for a light breeze is a good idea, however this isn't all you need to do it just slows them down by preventing mating! Clean your grow space with a bleach cleaner! 1 tablespoon of bleach to 1 gallon of 95°F from a spray bottle or mister works just fine! If you are looking for an application method then Azamax is a well proven product for fighting off Spider mites. Lady bugs! Although you have mentioned you know about their help so ill skip them =p Remember 3 things! Clean grow area - wipe of leaves with insecticidal soap - and Insure there is Moving Air to slow spidermite mating! DO NOT UNDERESTIMATE THE NEED FOR MOVING AIR. I'm sorry to see this situation get as bad as it has. If you DO plan on resetting and starting over don't forget to treat it like the infection it is and get rid of all instances of the infected plants to protect your next crop.

Fuckin mites. Hate them so much! You did the best you could, you could try containing the outbreak by using neem oil. (I once had to throw out plants cause I was being an idiot and applied a pesticide that was supposed to be used AROUND the plants and I used it directly on the soil. We all have mistakes haha.) I completely ditched soil because of the area I live in which is near a lot of woods so pests are extremely common. If you use hydroponics setup the pests won't have an area to bed and make home so they are less likely to contaminate hydro, they can't live in water. An easy hydroponic setup would be general hydroponics, its prebuilt, cant fuck up building it. If you get it poke a few extra holes in the bottom so the roots can submerge in the hydro and add an airstone. I highly highly recommend switching away from soil if you have pest problems. Best of luck! =)

Hi @NullHypothesis! Isolate the contaminated plants in another room if you can, otherwise the colony will spread and invade all of your babies. Predatory bugs will help you to get rid of those mites, but you will need to work in a closed environment, this usually leads to heat and poor airflow issues, which are the perfect conditions for mites to reproduce and lay eggs everywhere. So before running into this approach, make sure your setup will work within those conditions. In this situation, I think I would continue the chemical treatment for 2-3 weeks with a good airflow and cold temps, then close the environment (if your lights don't produce too much heat + if you have enough fans inside the tent to create a slight breeze) and release the predatory bugs for 2-3 weeks. This should work until harvest but remember to clean and re-clean your room after this run, those bastards can hide anywhere and come back at anytime if your room is not perfectly cleaned. Hope this will help, keep us up-to-date and happy growing 👊

Hello ! You did everything you could in that situation , I mean you used a pesticide which have quick results (don't use it too much , 1 week max) , you used neem oil ( 1 part neem oil for 9 part water ) so it also kill the mite and some of the eggs and will prevent them to get back ( use it every days if necessary untill the mites are gone and even 2 or 3 weeks after ) , you will soon have predatory bugs to make a everydays work in your grow space. The only advice I could give you is to finish your pesticide and neem oil treatment before you introduce your predatory bugs in your space : you don't want them to flee because of the neem oil or die because of the pesticide ( and chek how many time does the pesticide remain in the plant , some can remain 6 weeks others less or more, it can be bad for your health ). I would not recommend you a 4th agressive method but it will be good to try to keep the leaves of the most affected plant from touching the others plants leaves. And to finish here is a link with a lot of method available and they tell you what to do and not to do 👉 https://www.growweedeasy.com/cannabis-broad-mites 👈 I hope it will help you to get rid of them 😁👍
