Trace is generally dosed using Fe as the proxy for all trace nutrient levels. If we look at Fe ppm as the proxy instead of mL/10 gal. the comparison of dosing is more obvious. For calculating trace I used, http://rota.la to get the following dosing comparisons using Fe as a proxy for all trace. Unfortunately the calculator does not list AV Envy at this time.
Aaron - F. Comp: 0.08 ppm
Brandon - CSM+B: 0.08 ppm
Cavan - F. Comp: 0.17 ppm
Kris - AV Envy:
I wouldn't consider this to be a trace supplement.Mike - CSM+B: 0.21 ppm
Nick - CSM+B: 0.14 ppm
My DIY for nutrient solutions can be found in my journal "Mike's 30 g"
