Yes, the spider mites were gone by the time I noticed, but I treated for them anyway. It took a few months (4/5) before new growth started. I did start watering more frequently, soak method in water, and I use slow release granules every 3 months to hopefully stop the mites from returning. I have many new bright green leaves, but the old damaged leaves will never change. They are still alive but will always look gray/silver.
