I'm a bit confused whether or not I need to add postassium.
I currently am using the EI method with the following dosing for my 55-gallon tank:
1/2 tsp. KNO3 3 days a week.
1/8 tsp. KH2PO4 3 days a week.
Traces 10ml 3 days a week.
Using the fertilator and Chuck's calculator, it seems as though I'm not getting close enough to the recommended level of 20 ppm for potassium. I just received some potassium sulfate and was wondering if I should use it to boost the potassium level up to 20 ppm.
BTW, I'm just starting week three of the EI method and have noticed a major improvement in plant health and growth. I even had to prune a few of them during today's water change.
Cheers,
