It's not an argument, and more of a guess than a theory. I can only go by what I see in my own plants. I begin upping the feeding at about week 5 and continue until week 7 or so (or when pistils are browning in earnest before cutting back.....That's when I see tip burn that I wanted..(pushing the plant as you say).
If I overdo feed (Megacrop and Ginormous + kelp+ Sweet+ Herculean Harvest) before they are ready..they let me know with burnt tips.
I did over feed a Purple Badlands last grow, and she stayed green throughout a 3 week flush (with Flawless Finish too). I haven't smoked any yet, but hopefully I won't be tasting Megacrop. She was one that did not do well with the Liquid kelp, while her tent mates did just fine.
We each do it differently..The important thing is that we get good medicine and have fun learning in the process.
