Now, take it for what it's worth because I am a new grower to Cannabis, having battled spider mites the entire veg of my last grow that's what it looks like to me. If it is the case, it will be imperative for you to be diligent with your treatment. I used neem oil (1 tablespoon per quart spray bottle) and I only had success when I decided to be consistent with my treatment. Oh... that neem oil will burn under lights just apply before dark. But hey... you probably already knew this. Peace... good luck. 👌👍👊
