I always see the little dots on the top of the leaves well before webbing. I had sooo many issues outdoors with them, I found that is the first tell that there are mites.. By the time they are webbing up my weed, it means there is a severe infestation and it's more of managing them till harvest.Main thing to watch for on spider mites is webbing, usually see that before you see them.
