You really went all out with the amendments! I started off that way too, but for the past couple of years I’ve been amending, topdressing with only kitchenscraps, tree leaves, grass clippings and dandelion leaves. All free! Contains plenty of all essential minerals and more, it works fine! 
Add a little of everything, I wouldn’t use more than a small handful of any of the amendments, don’t go overboard, what you have in mind seems great.
I’d add half a bucket of kitchenscraps too.
Once it’s all mixed, keep it moist and let it rest for at least two weeks, ideally a month, while fluffing it up every day or so. The amendments need to break down and the soil will be a bit too active for a while to grow anything in it.
Cover it up and keep it moist. When you grab a handful and make a fist, when you get one drop of water, that’s when it’s perfect moisture wise, keep it like that throughout!
Feel free to check out my current grow journal, any questions are welcome!
