Question about Fertilizers
So this whole fertilizer thing confuses me. I understand that there are macro and micro nutrients that my plants need. I was looking at Greg Watson’s Fertilizers and I was just going to get the PMDD Pre-Mix but after some research concluded that it would be better for me to dose separately. So instead, I am looking at getting 1lb of Mono Potassium Phosphate, 1lb of Potassium Sulfate, and 1lb of CSM+B Plantex. I have some nitrates in my tank so I am not buying that as of now.
So I guess my question is, do these cover all the nutrients? Am I missing anything? If so what? Thanks for you help.
