I had those bugs on my plants for the longest time and had trouble finding out what they were... Eventually i figured out that they are a type of leaf hopper. Apparently there are thousands of different kinds. But basically they are a small, flying grass hopper that chews holes in your leaves. I picked up a common pesticide called "Seven" and applied it to the plants via a sprayer. As long as you stop using it 10 days before harvest your bud will be safe to smoke. Hope That Helped
