Agreed on 1, for the most part, if you are not actively fucking the balance up
Dunno about 2, haven't tried yet, PPM and no nute burn and no stunted growth seems to disagree (she's able to handle it), not sure what happens if you don't give it.
3 is completely backwards in my experience. I have plants that get N abundance when I give the prescribed amount in bloom, which is half the amount from veg. I go even below that, check my Blue Cheese for what I mean.
Rather than trying to change your mind, I'd like to ask for your supporting material, as it flies in the face of everything we know about indoor gardening?
