Hi guys,
Sorry if this is a silly question, but I'm having some issues in my tank and I've decided to review what I'm dosing and I'm now thinking I may be underdosing potassium. I copied the below table from a post of @Zeus. that I found in a past ukaps post. Everything I have read has indicated that the potassium from dosed KNO3 will be sufficient. I've been dosing to roughly Clive's EI target - I've been dosing 22.5 ppm NO3, and putting this into the rotalabutterfly nutrient calculator, this equates to 14.19ppm of K. When also factoring in the 3ppm weekly dosage of PO4 from K2PO4, the calculator says this provides 2.47ppm of K.
So if this calculator is correct, then I am underdosing potassium by nearly half. Does this information sound correct? Because if so then I think I will try adding some K2SO4 to boost the levels to 30ppm.
I guess I'm confused by this because surely if the calculator is correct, then EI recipes should also include K2SO4?
