* I am not sure how much Flourish/Flourish Iron to dose. Does anybody have a recommendation here?

* I'm guessing, to start off with, it's better to be generous and work at reducing the amounts added rather than increasing them?

Nitrate - Aim to dose 2ppm per day. Total 14ppm per week, 2X worse case for zero uptake 28ppm.

Phosphate - Aim to dose 0.2ppm per day (i.e. 1:10 ratio to Nitrate). Total 1.4ppm per week, 2X worse case for zero uptake 2.8ppm.

Potassium - Aim to dose 3ppm per day. Total 21ppm per week, 2X worse case for zero uptake 42ppm.

Thanks heaps,
Scott

 

Forgot to mention, 1 teaspoon of KH2PO4 in 500mls water gives me 0.02ppm in 405 litres per ml.
