Content marketing: Google search indexing stalled?

I'm leaning heavily on content marketing for growth, but I'm having issues with Google Search indexing. In general, blog posts are taking weeks to index, and one post in particular seems to be stalled indefinitely.

The pages are listed as "Discovered - currently not indexed" and validation status is "passed". The posts are original, the link structure is a simple blog, I can't imagine my tiny 7 page blog is overloading the crawl budget, so the only remaining guidance is to just...wait.

Anybody else seeing this? Any advice on how to speed the process along?
