can definitely tell they're healthy. Your leaves are gorgeous. That waxy shiny texture on them, means healthy cell structure, which should make them more resistant to pests. Tougher cell walls mean tougher leaf surfaces.
Believe it or not, plants put out a certain frequency when they're healthy and when they're sick. Spider mites can sense these frequencies and tell which is the weakest plant to start chewing on, and will start their infestation there.
I see MMJ beat me to the Jefferson "cultivator" quote above. Nice job Mike. You've got a green thumb for sure.
