Im finishing my 2nd grow and have only used supersoil, and have grown 10 different strains in these 2 grows.
Renfro and many others here have helped me directly and indirectly, ive read so many threads on so many subjects im like a stalker towards you guys lol, and you dont even know it lol.
One of the more interesting parts of this discussion is that it is almost always soil growers, often organic, sometimes even no till, that preach at a religious level about its success.
I too chose supersoil as a starting point because once I did the hard work getting soil built, i would be free of all the concerns of what to feed, how and when. It has worked very well for me. But it is far from perfect.
And the yellowing in supersoil in mid flower is real, and is the subject of a lot of discussion as to why -- is it ph, is it underfed, is it naturally yellowing earlier than nute grows?
I'll say this. I clearly hear the OP repeating my mantra it was done for convenience! Readily admitted. Me too.
There is a big, important difference between telling oneself a story about how the way you grow is superior, and does not require ph or anything else, and understanding that a holistic view of gardening -- being agnostic about method -- is the key to overall success.
Maybe as you think, nutes are never needed or organic is superior. Except every hydro grower can prove to you they can grow faster, have more control and as renfro suggests, actually influence the plants nutrient uptake beyond what it "wants."
I will not limit myself and will NEVER say organic is better, easier or in any way superior.
I know what I know, and am open to and welcome learning more. I want to understand nutes too, because it will teach me exactly how nutes work. Organic can shape the result with amendments, hydro can directly affect the result. Making hydro superior in this regard.
For me to believe organic is superior would require that I believe human performance and growth is best done organically.
Is the strongest, fastest, most agile humans ones that never took a supplement? F no! Ever seen the bodybuilding events where they have the pure athletes up on stage with the 'roid monsters? Yeah about 100 lbs difference of pure muscle. Organically it is not possible to be the biggest, most cut person in the world. It is only by forcing the system chemicals and a ton of healthy food that ther athlete reaches a performance level beyond what can be achieved organically.
I respect life and organics but am not a slave to it. Im open to there being a combination of methods that can and will always be superior.
My advice since this thread is full of it is to pull back on the preachy everybody should understand organics...they do my brother.
They see past it, to something less pure and more effective.
