Left C when you did your calculations did you take into account that your dosing solution was exactly 1/2 the strength of the 500mL solution?

Kinda of the ass backwards way of doing it.
Hi LilLou!

I started using that screen but I got all tangled up. My think-o-meter is slipping a little and my memory gland doesn't work like it used to.

I used the first screen on the fertilator. I entered the amount of each fert in grams from the formula and for the water volume, I used 37,850 L. This shifted the decimal place three places. 37.85 liters is 10 gallons and 1000 ml is 1 liter.

This is a shortcut way to look at the calculations that I used with the fertfriend:
(37.85 L per 10 gallons) X (1000 mL per L) X (10 gallons per mL dose) = ppm per day

This method made the conversions very easy to do.

I basically got what Edward says that each dose adds.

This is what I got: - - - - - - - - - - - - - - - -Edward says:
NO3 is dosed at 1.05 ppm per day - - - - - - - NO3 is dosed at 1.00 ppm per day
K is dosed at 1.41 ppm per day - - - - - - - - -K is dosed at 1.33 ppm per day
PO4 is dosed at 0.11 ppm per day - - - - - - - PO4 is dosed at 0.10 ppm per day
Mg is dosed at 0.11 ppm per day- - - - - - - - Mg is dosed at 0.10 ppm per day
