Nothing the plant will be finished before it gets into the system. Yep you have to think ahead like playing chess. It would help with the next round of veg though. I tend to load up a bit more heavily at the start of Veg and then flower, same with the bacteria, and then let the plants cruise along hopefully with that.
I dont think anyone is saying eliminating the soil portion, I think its about buying a jaws mix, and adding it to the soil you are making. It would help initially to have, as it is like a ready charged battery, the plant can use while the soil and bacteria is getting up to speed but small plants would get enough food just from the EWC at the start.
I load up on gypsum as it has no effect on soil PH.
Edit, @BDGrows if you are looking for inspiration, Stonedmason has just started a no till grow. Heres a link.
