Hi SoulSurer8
It all depends on how frequently your pages are crawled by Google. If you search for a page in Google and check when it was last cached then this will give you an indication of how long it may take. Under the result in SERPS there is a green down arrow next to the URL click that and hit cached. (see image attached) This will bring up a page with a date at the top which is the last time that Google cached the page. It will depend on how deep the structure is, so if a page s three clicks down then, of course, it will be indexed less frequently than the home page.
Check a few deep pages and compare them with the home page and you will see that in some cases it has been up to 6 weeks since the last indexing.You can speed this up a little with a Google fetch from Search Console on particular pages but that is the reality.
