"Fried" foxglove leaves, yellow stippling on hollyhock, and bronzed juniper—all point to spider mites, even without visible webbing (webs are rare outdoors). Mites suck chlorophyll from leaf undersides.
Blast leaf undersides with strong water spray every 2 days for 2 weeks—mites hate humidity.
Hexakis (Ortho Systemic Insect Control) is effective if needed.
