One slight error. If you are adding that whole list that is...
What you need to do is act as if that target number is a total.
Where you have "Do I need this ?" that is optional.
But if you use it you need to add the results from the KNO3 AND the K2SO4
to get your target amount. That much extra on "K" won't hurt.
But on "PO4" you don't want to add over the target. At least till you find
a related deficiency.
This list is a normal list for EI.
People often use the K2SO4 to regulate the nitrates.
For example: my tank gets 1/8 tsp KNO3.
But instead, I use 1/16 tsp KNO3 and 1/16 tsp K2SO4.
But actually I found this gives me a red color when I test just before the Water Change.
So... I use 1/32 tsp of KNO3 along/w 1/32 + 1/16 tsp of the K2SO4 and that
gives me a test result that is light Orange...10-15 ppm.
When you use that calculator, you can select "the result of my dosing" instead of EI.
That will allow you to convert to tsp. I just do it this way because I'm not going to sit down/w a scale each time I do ferts.
So to use the K2SO4 also you would do percents of each to reach that target amount.
Is that Rotala that gets curling leaves ?
