Having a new setup for 5 weeks is not enough time to see what is working and what not. You will see changes in coming months. Aside from that, dosing daily 0.25 ppm Fe is a lot and it may start accumulating and cause problems later. The usual Fe dose is 0.05 ppm (0.01 – 0.10) a day.
Hey Edward good to see chime in. And I agree, five weeks is not long enough to come to many conclusions.
And 7 ppm NO3 and 2.1 ppm PO4 weekly is not that light. I'm at 10 NO3 and 3.5 PO4 and folks think I dose EI. Fact is very few blindly follow EI, and most dial in what works best in their particular tank and mix of plants.
Also agree with Edward that 1.75 weekly is far more Fe than any tank I know needs. Doubt you need that much K either, but who knows?
I will say tank is looking good. Expect a few bumps and bruises along the but it's a great start.
Keep the updates coming I look forward to following along.
