Help Micronutrients management

[nivliw]

Hello guys I’m wondering how can I know that I’m not giving too little or too much micros or accumulating them to abnormal levels, I have the hanna digital test for fe however someone was saying that it doesn’t detect all forms of it. So what can I do about it? Because as far as I can remember someone was saying plants line reneickii mini is sensitive to high fe levels

Trust the dosing total and water change volume. .45Fe as proxy is well known to be a good spot to be. If growing AR, and it does that twist thing, you can lower from there.
