Late flowering spider mites

If you can take your plant outside you can spray it thoroughly with a garden hose & sprayer nozzle. Use the water to physically blast the buggers away. This won't remove all of them but can get rid of many. Then move the plant back inside and begin more serious treatment. I have heard of using soapy water and I've heard of alcohol and water but never both at the same time. I think the alcohol might be preventing the soap from doing it's job. When applying either the soap OR alcohol solution use a spray bottle or pump sprayer to thoroughly soak the plant and leaves. Make sure to focus on the bottom sides of the leaves. Really get the air moving around the plant. They have a hard time reproducing in wind and thrive in calm, moist air. There are several insecticidal sprays available specifically for cannabis. I have never used any but you can look into it.

Long as there not out of control webbing everywhere ? How meany plants you dealing with if just one just manually wipe them off next time you grow get some predator bugs to kill them off at start of grow cycle
