Yessir, for young transplants I usually either do happy frog or uncontaminated old soil from a previous run.
Let's say you take a cutting that is established and ready to be put into a nice comtainer, I usually use 1 gal smart pots, they are about 9-10 inches tall, i place 3 inches of strong soil, then 2 inches of ewc mixed w canna coco as buffer layer tha the roots will explode through, then the rest is a mild soil like happy frog , or seed starter mix, I love doing this process because I focus on what I'm doing and give the plants some serious love.
There's a million ways to skin a cat though , but I did this outdoors , dug 50 gallon holes and planted some bluedream and I can't believe what came of It. planted in first week of july, plants were 18 inches tall and only 2 foot wide, to start and by mid October the chop came early due to rains, smallest plant yielded 2.5 lbs, largest 4+. got a late start last yr but this yr they will go out as soon as photoperiod is on, organics can still yield if you really try, the quality is just so much better too Imo. Enough Ramble, good chatting man. You got my brain going and I'm ready to sketch some grow room designs lol. Later yall
