Soil: Dilute app. 1 teaspoon TerraBiosa per one gal water per 40sqft area (4 qm). Deploy regularly, preferably once monthly.

I mean looking at the dosage it looks like you'd be using a drop of it unless you're running a farm.

I don't think you're going to find anyone who's used that specific amendment. I don't see anyone using it for cannabis with a quick google. You'd probably have better luck reaching out to the manufacturer.

Maths to ~1:500 to 1:1000 but ingredients are fine... One thing to keep in mind, a lot of regulated markets have odd definitions of stuff the end result is folks doing products like these to skirt regulation. The downfall is you often don't get a good analysis on the products, because of their formulation, because of their labelling, and because of how they are skirting regulation.... a lot of the signalling molecules in these types of brews have critical levels transition to detrimental levels very quickly (like a doubling of PPM in a single hormone). Long story short, I'd lean to the 1:1000
