To update, the leaf spotting was pretty much entirely from spider mite damage, and the yellowing on the healthier leaves seems like it was from a lack of nutrients. I've been regularly hitting the plant with a 20-20-20 fertilizer. I tried ladybugs but the ones I got locally were mostly dead in the container, and the few that were still alive wandered off within a few days. I went back to spraying with an alcohol-water solution. I also did a lot of pruning of the most heavily infested leaves. Any time a leaf turned more than 50% brown I pulled it off and disposed of it. Between the pruning and the spraying the spider mites seem to be under control now. A lot of the original growth on the plant is dying back, but I've gotten a lot of new growth around the base of the plant. Unfortunately all the baby hop cones I had in development have died, so I'm not expecting any harvest this year. It's a first year plant though so I wasn't expecting a lot.
FrFtr28, I didn't notice much purple coloring to my leaves. It may just be the pictures, but in person the leaves had more of a bronze color to them.
