need some feedback, please help!

thanks for stopping by. i was moving my plants around in my room last night and found that 1 of my blueberry's have spidermites. i have 18 plants total in there so probably by now they've spread. i'm 4.5 weeks into 12/12, so i want to be careful on what i do to treat them. i'm going to get some lady bugs on wed. to help the issue and i just picked up a fogger. pretty hesitant on using the fogger, i think it's pretty harsh and this stage into flowering don't want to screw anything up. i do have neem oil also, if i use this how much should i dilute it and when to use it? my lights come on at 8 pm so i want to have a game plan by then. thanks for the info.

Don't use the chemicals at this point. The Lady Bugs will help a lot. Use plain water in a sprayer and spray underneith the leaves. You can also gently wipe the leaves off with your hands. If you weren't going to use Lady Bugs, I'd suggest that you go to Home Depot and buy several No-Pest-Strips and hang them in the grow room. They give off a vapor that kills Spider Mites ... but they will also kill all the Lady Bugs as well.

I would spray the plants with the neem oil solution, wetting the undersides well, since you are on Day 32 it's early enough that it won't affect your buds.

Mix the neem oil at 1 teaspoon/quart of water, plus a few drops of dish soap. Shake the bottle constantly when spraying. Turn the brights off, spray plants, and let dry before turning on again.
