I whole heartedly agree with you, for the most part. When I was in the military, I remember saying to people, all the time: "If it isn't broke, don't fix it". These words are true and effective in the grand scheme of things. I'm simply working my way in to the abstract here. Nutrients are a tricky thing to discuss, so let's start with a general statement.
From the outside, one may be inclined to say that there is no difference between nutrient systems, as anyone can do extremely well or extremely bad with any nutrient line. This has been seen time and time before. This post has all the right ingredients to perpetuate that idea. My only argument, is that there are too many variables to consider that a measurable truth. There are way too many things that need to be controlled with each individual grow to say that nutrients really won't do anything to your final crop, and that switching them won't either. It really takes a desire to maximize your potential when talking about making changes to a system that is seemingly perfect already. Lordjin may not need to switch nutrient lines, but if I was some sort of grow-observer with a giant check-list of areas needing improvement, that may be one I would encourage him to investigate. The Lucas Formula has been around for a long time, and has done amazing things since then. For the small time, in-house grower, with one light, all the accoutrement, bells and whistles, I would say that there is definitely room to step up from the Lucas Formula food system.
But, having said that. No one is saying anyone needs to step anything up. Lordjin's grow looks awesome, and there is no doubt in my mind that he will be smiling from ear to ear when he finally gets to enjoy what is looking to be some ridiculously awesome weed. I do see a lot of potential though. There's a difference between head-stash growers and commercial growers. I fall way, way, short of commercial. This gives me much more time to really, really perfect things. I could find the cheapest thing out and make it work, but that's what people do when they're growing 500 plants. That's great and all for growing product you want sell, because it really doesn't make a huge difference there. But when you're growing product that you do not want to sell, it makes a VERY big difference. My two cents. Sorry for ranting, a bit stoned, this early, I know, I know....
