I've seen a visible decrease in live spider mites. Spraying Captain Jack's Deadbug every 3rd day. 2 treatments so far. I took a sample bud from the very center of the plant to examine with my loupe (still need to order a microscope). From what I can tell, most of the trichomes are cloudy. Drying the sample in a brown paper bag. I still don't know if my leaves are turning yellow due to light stress, nutrient deficiency, or because the plant is close to being finished. I've clipped a bunch of leaves off both from yellowing and because there were a bunch of visible spider mite eggs underneath.
There's been a definite decrease in spider mites after 3 treatments, but they're not totally eliminated yet.
