Hi
@BillMonroe! Well, since your plants are already in the flowering stage, you can't use neem oil and should avoid spraying any chemicals. However, spider mites really hate water, so if you think that mold won't be an issue (good airflow + low relative humidity) you can spray clear water when the light turns off and/or when the lights turns on. Another thing they hate is wind, so I'd recommend to use a tiny fan and create a continuous breeze onto the apical summits. These two tricks won't solve the issue for good since all the mites are not going to die, but it should prevent them from multiplying and ruining your crop. You will need a good cleaning session with a vacuum cleaner and neem oil + soap after your harvest. Hope this will help, keep us up-to-date and happy growing 👊
