Like trying to sort out all the confusion and choices? Never really had that problem, uh, lighting issues and providing all 16 essential elements. Been doing this for decades. Ever wonder why I don't do SCROG, coco, DWC, LST, and all the other gimmicks? Cause it has too many shortcomings and bullshit you have to fight. Enjoy your challenges....I'm a KISS man myself.
Great link and some really excellent info, some of it corroborating what I've been preaching for years, actually for decades:
Tissue tests conducted in 2003 by Advanced Nutrients through BC Research Inc on numerous cannabis strains demonstrated that cannabis plants require far less P than is present in many hydroponic nutrient formulations and additives. The tissue tests also demonstrated that N, Ca and K are required at far higher levels than P and P, while required at somewhat higher levels in bloom than grow (as is shown in numerous studies), is required at far lower levels than would be expected. Another surprising outcome was N requirements in flower (re cannabis) were higher than previously believed. These findings contradicted conventional beliefs among hydro industry professionals and others that high levels of phosphorous are required to achieve optimal flowerset in hydroponic settings (among other things).
duh....
Snake oil sons-a-bitches might finally be starting to get it. Won't matter though. They'll still sell the formulations that they do because they think it's what the (ill informed, usually young) customer wants. You'll read many a post where I've used and am an advocate of such formulations as 20-10-20 or
18-4-9 from start to finish.
Also, I'm using DeltAg products or let's say I'm experimenting with them based on a generous care package from the company. Me and Johnny went around on his sales pitch about how silly other's chelates were compared to his use of organic complexors.

Yep, this too was an excellent read -
CHELATED MINERALS VERSUS COMPLEXED MINERALS
Still left me a bit confused but the conclusion is that chelates are more effective than complexors....not that I really care. Too much of "here's the scoop but only if XYZ element is not present......" Thankfully my plants can't read.
Give me a pot of soil, some food like Jack's or a slow release Polyon or Osmocote food and that's all I need.
You may now step down from your pulpit.
