"Generally I dose based on light level and plant biomass.
This is something I have a feel for.
I cannot teach it.
But it also is not critical either."

Although you (TB) make some more quantifiable recommendations in 
other posts, this particular quote is somewhat undefined in terms 
of dosing. (It's as fuzzy as the term 'soil' when people say use 
backyard dirt, which is why I don't like that method.) But using 
your other recommendations I can get close enough dosing the 
water column.

I am wondering if there are any quantifiable lessons to be taken 
from hydroponic farming. What they do is not that far different. 
Unfortunately, the online sources I visited don't list 
ingredients in their colorfully named products. But I suspect 
they've invented this wheel a few times already.
