To the OP, I fully agree to what has been said by these two wonderful people above, and might only reinforce, but here goes. Forgive my ramblings haven't posted in a while!
I've been in water only (save Fulvic acid, aloe, malted barley powder, and silica) soil beds indoor for roughly a year now. I had planned on going no till (read lazy), but my initial mix was getting a tad on the muddy side. So I amended recently with more pumice (one cubic yard) to fluff it up. While I was at it I added roughly 25 lbs of basalt rock dust, 4 lbs alfalfa, 4 lbs crustacean meal, 10 lbs fish bone meal, and 2 lbs kelp meal to 200 square feet of soil. The worms and company weren't happy with my diggings, but the plants are loving the added aeration it seems. I watered in with ogbiowar foliar pack for good measure. It sat for three weeks while clones were rooting. I made the best of a cloning mishap that caused a delay. Otherwise I would have just added the pumice only and top dressed the rest. In the future I plan on adding amendments to the top in small quantities. I top dress worm-castings too, so I might have to add more pumice eventually. Time will tell.
After every round I put the fan leaves and stems/stalks back on top of the soil after trimming is done. It's pretty cool and saves water acting as a mulch. I have tons of random plants growing from the soil as well. The place I get my worm-castings from is right down the street from a grocery store. The guy takes all their spoiled produce and feeds it to his worms. We're talking a thousand pounds of produce a day. So when the worm castings are added to the soil mix you get all kinds of cover crops from the seeds in the produce, and from his farm. Grass, dandelions, grapes, cucumbers, watermelon, clover, tomatoes, and tons of other plants I have yet to identify. Anyway these get overgrown by the intended crop and added to the soil mix.
Oh also I leave the root-balls still in there. If they get in the way during replanting I toss them on the top of the soil, next to the new plant.
