Malted barley does more than you think it does
Been top-dressing my no-till beds with malted barley flour for about two years now and honestly it changed how my plants move through veg. You just dust a thin layer on the soil surface, water it in, and the enzymes it releases help break down organic matter and stimulate root growth. One cup spread across a 20-gallon pot every couple weeks is plenty.
The reason it works is the barley contains natural cytokinins, which promote cell division at the root tips. I noticed faster recovery after any kind of stress when i started using it, transplants especially. My last run of Banana Punch bounced back from a rough re-pot way faster than anything i'd seen before.
For what its worth, you don't need to mix it in. Top-dress only. Tilling it disrupts the fungal networks you're trying to protect in a living soil setup. Let the water carry it down slowly.
You can usually find it at homebrew supply stores, same stuff beer brewers use. Way cheaper than any bottled enzyme product and it actually works.

Been using malted barley for about a year now and yeah the enzyme activity is real, but i want to pump the brakes slightly on the cytokinin angle. The cytokinin content in malted grain is genuinely pretty low and the bigger driver in living soil is probably the microbial bloom the starch triggers more than direct cytokinin uptake. Not saying it doesn't work, clearly it does, just the mechanism might be a bit more indirect than it reads here.
What i will say is the effect on the rhizosphere is noticeable. My no-till beds smell incredible after a barley top-dress, that sweet earthy funk that tells you the microherd is going nuts. And plants grown in a thriving micro environment tend to produce better terpene expression in my experience, that part i've seen consistently.
One thing worth adding, grind matters. Coarse crush versus flour behaves differently on the surface. Flour breaks down faster and hits quicker, coarse takes longer but releases more gradually. Depends what you're going for.

Two years in and I'd be curious whether you've noticed any mold on the soil surface with the flour. That's the one thing that slowed me down from using it more aggressively in my tent. Higher humidity plus flour sitting on top is a recipe for white fuzz in my experience, even with good airflow.
I switched to just doing it every three weeks instead of two and backing off the amount a bit during the wetter parts of the run, and that mostly solved it. But worth mentioning for anyone growing in a more humid environment.
The recovery speed thing you're describing, I've seen the same. Whether it's cytokinins or just a happier microbial situation, I'm not really in a position to argue the biochemistry. All I know is my living soil beds outperform my old synthetic runs in ways that are hard to pin down to any single thing. Malted barley is probably part of that picture.
