Which two ferts for auto dosing?

I will be setting up my first planted tank(60g cube) soon which will be high tech and it will have an Apex dual doser (DOS) with two 2 liter reservoirs.

What would be the best route to take with ferts? Price isn't really a concern. I could mix dry parts myself or buy pre-made big brands.

I'll be using Aquasoil, Radion XR15 freshwater LED, a second DOS for auto water changes/top off and CO2.

I haven't really dove into what will go into the tank for plants and fish yet other than seeing a few must have plants.

Crinum calamistratum
Aponogeton crispus 'Red'
Pogostemon helferi red

I am setting up three planted tanks(11g, 15g & 60g) the same way so I can tailor everything for each tank depending on what I come up with that will work together and require the same parameters.

I have a PhD in crazy.

I would use standard EI dosing solutions. The drip change system should be set to change 50% water per week.

You will need two solutions. A micro and macro solution.

The chemicals you will need are KNO3, KH2PO4, K2SO4, Plantex CSM +B and DTPA iron 10%. Depending on your tap water you may need GH booster as well. You can obtain them from several sources. I prefer a user here NilOCG from NilOCG Aquatics.

For the solutions add the amount below into one liter and dose 20ml of this 2-3 times per week.

Macro Bottle
Code:
KNO3 127.303 gm (approximately 24 1/2 teaspoons)

KH2PO4 19.4 gm (approximately 3 1/2 teaspoons)

K2SO4 51.87 gm (approximately 8 1/8 teaspoons)
Micro Bottle

Code:
Plantex CSM+B 39.85 gm (approximately 9 1/4 teaspoons)

DTPA Fe (10%) 26.02 gm (approximately 6 1/16 teaspoons)

Thanks. Bookmarked.

My city water basically has rocks in it (between 400 & 600 ppm) and my 3 stage RO doesn't get all of the TDS out of it.

If you're going to use R/O then you will need to add a GH booster. Add enough to raise dGH 2 degrees once a week. If you use GH booster then you can eliminate the K2SO4 from the Macro solution. GH boosters typically contain this.
