just so ya know: that which comes out of your MEP contains more (concentrated) Cannabinoids than your starting material (see mass balance for why that’s not actually true) , and is therefor all “concentrate”.
I don’t know who handed you “mother oil” as a moniker, but it is not a term used outside of the lab you’re working in (least not one I’ve run across in the 10years I’ve been playing this game)…
“mother liquor” is that from which you have crystalized…so if you’ve not made “diamonds” you’ve not made mother liquor.
