I fully agree. I think that its always good to have a look at what some of the guys are suggesting and working from there. I use a pretty common soil mixture so a lot of what the guys do recommend is applicable to my process.
I think the main thing is that you need to journal a good amount of what you are doing if you want to dial in your approach. Bugs and plants problems are good indicators of you maybe stepping over a boundary, once you can identify what you gave the plant, how much of it and the impact it has had, you get a good idea of what works and what doesn't. That process of elimination is what gets you to where you want to be.
Its really hard to give out a perfect approach, everything is do different.
