Looking for good information on better understanding how plants use nutes

Looking to educate myself on tuning my nutrients, but haven't been able
to find any good articles explaining how plants use nutes and which ones
they need when.

Not looking for an explanation from anyone, just some good links to read
over so I can better understand what I'm feeding them and why.

+rep for good info!

Might have to invest in a book. I do recall a podcast called The Grow Report where the host broke down each nute and explained it's role. Was in the early archives.
