One aspect you will definitely need to monitor is plant nutrient content.
In my estimation plant analysis gives a better overall picture of what is
occurring within the entire growing environment.  The sampling should be
repeated preferably on at least a weekly basis.  A&M has capabilities to
analyze the tissue as do a multitude of labs within the U.S.  For research
studies, some labs will do the analyses free and some will do it at a
reduced price.  Also, try to select ones that use drying and dry ashing
systems.  Wet ash systems (microwaved) seem to give more variable results.

Monitoring the plant itself in this manner will allow you to make "finer"
adjustments to the system.
