Well, I feel for you bro...but I think these few insights could help put smiles on your canna-face..
If it’s possible for you to bring your plants outside or somewhere safe, you might even consider spraying off as many spider mites as you can, to get their numbers down before you start your main treatments.
Get a fan blowing over the plants and top of growing medium Not only do plants grow better with a breeze, great
air circulation is great for pest prevention. Spider mites love heat and stagnant, non-moving air. They can’t mate in windy conditions so a strong fan can help keep the infestation from getting worse. A breeze also helps pest treatments go better because fans help spray treatments dry on the plant.
Azamax is a time-tested way to rid your grow room of spider mites. Spray plants 15 minutes before lights out, making sure to drench the foliage under the leaves as well as the top of your soil. Use a fan to blow on your leaves to help things dry. Treat your room more than once, even if you believe the spider mites are gone. You can also add small amounts of Azamax when watering your plants, as it will not hurt your roots but will kill spider mites in the soil. You will need a mister (also called a “One-Hand Pressure Sprayer”) to spray all the leaves evenly.
