He's also running 15s. I've noticed that smaller no-till planters will eat through available amounts of certain amendments if they're in the first couple of cycles especially if they're pretty long term. I know if I'm running less than 10 gallons I have reammend certain amendments heavier or I'll see deficiencies. For example I have a 15 gallon planter that 8 months ago wouldn't have gotten anything through flower without issues, now it's some of the best soil I have as the nutrients have had ample time to cycle and become available again in amounts necessary for a blooming cannabis plant.That is about 2 cubic feet of soil. I'd say thats perfect. I would leave out rock dust. Coot said to add that only once.
This is also just my experience, our souls *edit("..our Soils.." Lol had to leave that in there for laughs)* will always be different as well as our environments so he may very well not have to add any rock dusts back into it.
