This is from another thread but I thought it worthy of starting a new one since it brings up an approach that is easily doable for folks and addresses Jeff's suggestions of the "just enough" approach.
You may wish to try the rich method and then back off in a controlled slow manner and try what Jeff suggested as "just enough".
Both methods have a similar approach and anyone can do it with a test kit etc if they watch closely.
I generally do things that way and then go back and test.
I tested for traces by taking care of everything else to excess, then added a little for 3 weeks, then added more etc until I had no improvement in color or health.
That was the max rate.
Try the minimum rate now.
Reverse this thinking and follow it backwards.
Add enough till you note bad or poor growth and then riase it a tad above that level.
This is often what is done with NO3 to get red color.
You should dose liquid stock solutions for accuracy and dose per 24 hrs or some consistent unit of time per ppm of dosing of whatever nutrient you are interested in.
Try each one individually first though, then try multiple set of changes.
