Default Do you have to dose fertilizer everyday?

I just started my first planted tank. 30G fresh water. I have T5 10000K 42W lighting. No CO2.
I have Cobomba caroliniana, hairgrass belem, Helanthium tenellum, Vesuvius and some Fissidians and Flame moss.

I am trying to understand all dosing before I buy all fertilizers. This is what seems to be the consensus.

20~40gal
50% H20 change-weekly
1/4 Tsp-KN03 3x a week
1/16 Tsp-KH2P04 3x aweek
1/2 Tsp-GH booster once a week
5ml or 1/16Tsp-Trace 3x a week

Questions:
1. If we do a mix of micro and macro every other day.. That's dosing everyday. Is that really necessary? Can plants really use up all the nutrients in a day?

2. Also, does it require 50% PWC? Some say 25%, some 50%.. Any points on that?

3. I am planning to use Flourish Excel. Is this good enough for carbon to live without CO2?

Thanks!
