Well, after a search and destroy mission, I have to report that I found NO spider mites anywhere.
No eggs, no webs, nothing.
I have the necessary magnification.
nothing.
They were only on the central cola of one plant that was so big I had to whack it up into three parts when I chopped it down yesterday. I need three or four more weeks to finish what I've got and then I can break everything down, fumigate and start over.
My buds are too big to spray now. If I see any more I'll try a little alcohol mist and see if that keeps them down. From the reading I've done, the reason some people have trouble getting rid of them is the eggs aren't killed by spray, so you have to treat again ten days after the first treatment.
I have enough bud to weather a storm like this
