Fungus in spruce
Noticed this whiteish substance on my mature spruce late summer. Now inner areas of tree appear to be dying out. Never any issues for the past 17 years.

I can't tell exactly what may be going on with your spruce from your photos. It could be sap or maybe symptoms of Admes mite damage. I would suggest you send a foliage sample to MSU’s Diagnostic Services to see if they can determine a cause. You will want to go to their website to see how to send a sample, www.pestid.msu.edu
Here is a link to information on Admes mite. https://www.canr.msu.edu/news/spider_mites_and_admes_mites_are_active_in_conifers
