EI dosing questions

I want to start working dosing on my tank but Iíve got a few questions.

1. What a good dose to start with. Iíve heard 7.5 ppm N thee times per week is good to start with but what concentration on P K and Micros should I start off with?

2. Should I dose macros and micros on separate days?

3. The tank is high tech but doesnít have much plant mass yet. Should I start off with a more lean dose at first?

1) I would recommend using the Rotala Butterfly calculator (https://rotalabutterfly.com/nutrient-calculator.php). It is very useful. Select DIY, dry dosing, and just use the Estimative Index option. It will give you the amounts to dose 3 or 4 times a week. If you'd rather create your own macro solution, it has that option as well.
2) It is usually better to dose on separate days as the Macros can interact with the micros.
3) You will probably be fine with full EI as long as you're doing weekly 50% water changes. If you're worried about your lack of plant mass, just reduce them a little until you get more.
