Is there a particular brand of bottle nutes you like for soil grows?
this is not at all where I want to position myself due to "advertising" bias etc
but I believe that a soil grow should be mostly organic, with as little as salts or acids used as necessary.
also, having a rich soil that contains feeds already in the form of dry amendments and bottles only for stimulating what's going on inside the pot, or pushing it into a specific region. like S Mg on the onset of frost to prevent some top pale, likewise P later.
Now if we increase specific ions in relation to the general formulae does that already imply a reduction of N? In one way - no - as the raw/netto feed of N is the same (or even more if we generally up EC from veg >> early flower >> mid flower.
But since ions exert a rivalry at the plasmalemma an increase of an anion could likely result in a decrease of nitrate for the plant physiologically.
There's so many different ways to look at these things. Also, this differentiation between veg & flower. Some grow-plans suggest upping PK booster at flower, which many will do right after going 12/12. Which I find totally wrong, the stretch phase resembles physiologically much more the veg phase, and due to the plants internal hormone boost, would require more of that (via +EC imo). A PK too early will just create deficiency/lock (see above), and then when I post in newbie sections about that gets oftentimes shit from hippies for "the evil N in flower" or "but the plan" from noobs. not reading the plant the fancy bottled schematic knows apparently better.
You see, when even the very definitions of simple terms vary then it's quite easy to turn ones own words around to imply what's not been wanted to be said...
