[APD] Re: excess
TB:" What are excesses? When does it become excessive?"
TW: "Hey, -you're- the science guy. But for me, it would be excessive at
the point where there is no perceived benefit. At the point where the
plants do well -and- algae is suppressed." ***EDIT: That should read BEYOND
the point where...***
SH: "Doing well isn't an either-on-or-off thing -- so I think the question
just comes back to how well is well enough? And that depends at least on
how much growth and pruning you can enjoy in any given period."
Yeah, but that includes some other variables, like the amount of light. I
like to run about 2WPG because it keeps things percolating along nicely
without massive pruning and without the stress of the higher light
balancing act. But somewhere in the mix of ferts is a place/range where the
plants do well, given the amount of light, and the algae does not. For me,
the ranges listed here work most of the time:

Except we seem to be creeping upward on the NO3 and PO4 numbers.
