Modifying Ferts?

[JoeQ]

I know I should have micro and macro days for ferts. And I think a separate iron day because something Cory said about macros and iron? But how bout supplementing? Can I add extra seachum potassium or Nitrogen to my macro days, then extra Iron to my micro days?

Yes you can. The macros are: Nitrate, Phosphates and Potassium (NPK). Therefore Potassium is a macro. It is the "K" in NPK. Nitrogen is also a macro and is Nitrate, which is the "N" in NPK.

Thanks, I'm aware of which are macros and micros, I just wasn't sure on mixing brands. It seems im running into to macro deficiencies again, even tho im dosing more than ever..... So am I correct in assuming that the only thing I need to avoid is mixing Iron (easy iron) with Nitrogen? And that I am safe supplementing that on micro days (FlorinMulti)
