Hey there that's typical of spider mites. Check to make sure by looking underneath the leaves for very small dots , if you see some then you'll know it's spider mites. Once you get spider mites, consider everything contaminated, the soil, the grow room, the plants, your clothes, everything. These things are so small they can fly through the air on the wind for a long distance before they reach you. It's very hard to get rid of spider mites, very very hard. There are these "folk remedies" like the neem oil, simple recipe, it's cheap it's bio, and of course it doesnt work and makes the bud taste and your house smell wierd. Another way is to use safe foggers which are a non bio pesticide and should be safe for humans, and anyway these dont work very well either. For both of these solutions, make sure you repeat the treatment every so often, otherwise they come back. The only real solution is to buy or find "live ladybugs" , these insects eat the eggs of the spider mites and eat the spider mites also, they can eat 30k spidermites each , and it's kind of the only thing that really works. When there is no food left for them they leave or die, but they dont contaminate the bud. So my best advice is live ladybugs, nothing else works - fight bugs with bugs - call it the biological warfare ! hope this helps bro ! :rocket:

Hey there @PureMedicin! I agree with the other that this doesn't look like a Fungus Gnat infection, but rather a spider mite one. Even tho the treatment is the same in most cases its very important to know the difference. As @SpinnerCarribean said - with spider mite you don't want to stop treatment when you think the infection is gone because they are illusive and can still be there! There are 2 possibilities the first is that you got unlucky someone accidentally tracked the spider mites into your garden. This possibility is the best in your station because it could be that you have a species of spidermite, like strawberry spider-mites, that are not a cannabis expert (two spotted)and easier to get rid of. The other possibility is that you got the spider mites from a clone or another Cannabis garden in which case its likely you have a more evasive species of spider mite and the treatment should continue well past the last signs of them. Whatever method (neem oil recommended) you use to get rid of the spider mites you can most likely use on your soil surface to Eliminate ANY chance of the Fungus gnats you mentioned as well. A sort of two for one. Just remember the Spidermites can take time and effort to get rid of. DONT SLACK ON THEM OR THEY WILL BE BACK.

Hello ! I was 1st thinking you were right about the gnats due to the leaves symptomes ( edges and tips burnt , brown/grey patches ) but your grow should have been slow down and your leaves should appear twisted what it not the case here. I bet on a spider mites attack , the best way to know how to treat is to watch under your leaves to see if you can find some bugs , if you can see them with your eyes then it isn't a fungus gnat attack and a simple neem oil spraying during a week or 2 will get you rid of your issue ( 9 part water for 1 part neem oil) but you will still need to treat after you think they are gone and also treat your grow area ans check it time to time to prevent them to getting back in. You need to know that they like heat and humidity so if you try to reduce the heat ( 40% RH is good) it will probably slow down the progression , and add a fan blowing around your plants , it will help. I hope it will help you :grin::+1:

Hi @PureMedicin! You're having mites. Probably spider-mites and/or broad-mites. At this stage of the invasion you must act quickly to try to get rid of them and plan a strategy for the upcoming weeks. Mites hate water so just spray your plants with RO water 3-4 times a day, and apply some neem-oil mixed with soap in your spray when the lamp turns off. Add some fan blowing a continuous breeze onto your canopy, they hate wind. These tricks should disturb them and limit the invasion but you certainly won't manage to get rid of all of them until your next run (grow room must be entirely cleaned). Pest prevention is an essential topic, you need a pest-prevention-strategy as soon as you plant your seedlings, during the first days. My strategy is pretty simple and consists in 3 methods: 1) I have an electric atomizer working 10min every hour to diffuse essential oils mixed with fresh water (a few drops of lemongrass, lavender, can find those oils in nature-stores or online). Those oils are repelling insects/pests, they don't like the smell of my room. 2) I spray neem-oil everyday when the light turns off, 10-12 drops of pure neem-oil mixed in a liter of temperated water, this oil is really efficient to kill/disturb/sterilize the invaders. Add some crushed garlic in the mix for an even more powerful effect. 3) I use a dedicated foliar spray (BioBizz LeafCoat) once every 2 weeks to create a 'transparent layer' onto the leaves and to protect them from spiders/thrips/moths/miners... Since I've applied this approach, I've seen ZERO invader in my room, and believe my it was a big problem in the past. Hope this will help, keep us up-to-date and happy growing :facepunch:

Agree to Mr. SpinnerCaribbean, No fungus Gnats. And Agree to the mites. on the younger leaves you can see the bite marks, the older ones are nearly consumed. Its hard to t rid of them. Because they are so tiny and do alot of eggs. They reproduce very fast.

its not to easy to get rid of them. And that they stay away. if you write you have the problem in all your grows they are " residents" in your growroom
