I don't know how much background info is needed for this question but just in case.
The tank is a 20H with sand capped soil, dosing excel and diy co2. I have about 40 par at the substrate. I had been dosing kents pro-plant and kents iron and manganese. Now I got some dry phosphates and nitrates and thought I'd try ei dosing.
I made a macro solution using Ei calculations: 10ml of the solution gives 7.5 ppm KNO3 and 1.3ppm KH2PO4. To account for no pressurized co2, I am planning on dosing 1/3, 3 ml, and follow the ei schedule.
My question is what to use for traces.
I have almost a full bottle of kents iron and manganese which has:
3% Soluble potash (potassium)
.24% chelated iron
tiny bits of Molybdenum and Zinc
I was given some micro/macro mix which
"Macro Micro Nutrient Mix is composed of equal parts by weight of potassium nitrate, potassium sulfate, Plantex CSM + Boron, and magnesium sulfate.
Plantex CSM + B is composed of 1.50% magnesium, 0.10% chelated copper, 7.0% chelated iron, 2.0% manganese, 0.06% molybdenum, 0.40% zinc, 0.04% boron."

I am not sure which would be best.
The Kents doesn't have all of the traces (missing boron and copper). I am not sure if tap water will have enough of those to compensate. Are those essential?
The Macro/micro mix has all of the traces but since it isn't independent of the nitrates, I can't really modify the dose too much.
Fertilizing experts, of these options, which would be the best for an EI dosing noob?
Thanks for your advice!
