Here are the formulas I’ve been following.
For the soil mix he left out the Perlite and Oyster shell, but I added 6qts Perlite and 1/2cup Oyster Shell
I'd be cutting that rose and flower crap right out. Top dress as an emergency amendment only. That's the only way to use it imo.
I'm an outdoor grower and mostly grow in the ground, so container planting isn't my forte. I really do think you could add a better amendment though.
Composted manure is really hard to beat as an all rounder, and takes several weeks to break down.
But having said, you might have to compost your mix prior to use. It does still get hot.
Don't be sleeping on nitrogen's importance. Especially in organics, because it's essential in microbial health. Your #1 source for nitrogen in soil, is rich organic matter.
I'll be honest. Besides aeration, i think this mix is lacking in rich organic matter.
Even something like blood and bone meal would be a good nitrogen source. It doesn't get too hot and smelly either. You can get away with a light dusting as a top dressing. (At least I do)
Watch what you're putting in those teas.
