I didn't get your tag on my name either... strange.
Oh well I'm here now. You've got a lot going on.
RO or distilled, it doesn't matter.
Ditch the baking soda, why add extra sodium when you don't have to.
Ditch the equilibrium, why add extra K (and maybe Fe?? I can't remember, I don't use the stuff) when you don't have to.
Ditch the ph down, you are taking one step forward and one step backwards using it vs kH boosting.
Ditch the crumby test kits, go with a pH pen that comes with the ability to be calibrated.
Ditch the measuring spoons, you could be out 100% by volume. By mass is what you need. A jewelry scale that comes with a calibration weight and accuracy up to 0.001 grams is what you want.
Per 1 US Gallon:
0.386 Grams CaSO4 - 30ppm Ca, 4.2 degrees gH
0.384 Grams MgSO4 - 10ppm Mg, 2.3 degrees gH
0.135 Grams KHCO3 - 14ppm K, 1.0 degrees kH
pH will be 7.1 / 7.2. You can go a little more then 7-8 degrees for gH, but my shrimp were happy in those conditions.
Here, get to know this website, you'll be using it a lot:

Hey guys my ph is 7.2-7.4, my gh is 3 and my kh is 2. I have platies and I just got plants today so how do I raise gh and kh without sending my ph through the roof? Also I’m confused as to how my ph can be so high with such soft water.
You can't have 1 mg/L CO2 in water, it's simply impossible. CO2 in water will always be about 3 mg/L or ppm due to gas laws.Ah yes. The eggshells are calcium carbonate, so with time my kh should go up. I only added the amount of MgSO4 that is typically used as a planted tank fertilizer (7g/100 L). I think my problem is low CO2 actually. With Ph (now 7.8) and Kh 2, I have.... 1! Mg/L CO2. Die, air stone! Hooking up some yeasties right now and gonna fashion a CO2 bubbler out of that. My plants arrived in really rough shape today and I want them to recover.
Both calcium carbonate and calcium sulfate will increase calcium ions once dissolved, so both raise GH. The carbonate will also raise KH, but the sulfate doesn't contribute to eitherI do not yet understand the difference between calcium carbonate and calcium sulfate. I assume both would provide calcium, but carbonate would contribute to KH and buffer/raise pH and sulfate would contribute to GH and would not raise pH. Speculation - not sure.
Would you turn off the CO2 bubbler at night? It is my understanding that you only want CO2 running when tank lights are on since plants cannot use the CO2 without light. It is further my understanding that CO2 based pH fluctuations do not have a significant impact on fish so using CO2 to moderate pH does not help anything. Of course CO2 is beneficial to plants so if that is your primary objective then it makes sense.
Again, just learning. Sounds like you know more than I do at this point. Take anything I say with a grain of salt.

My tap water tests 7 to 8 degrees for both GH and KH. But TDS is only 165. I would have expected it to be closer to 250 to 280. Could that be explained by Calcium Carbonate being measure in both GH and KH. Effectively double counted, but only counted once in TDS?Both calcium carbonate and calcium sulfate will increase calcium ions once dissolved, so both raise GH.

Oh right, didn't consider potential plants. I would assume that the lower the dissolved CO2, the faster the system would return to equilibrium, but the rate itself I do not know. Gas laws not being my forteI'll play devils advocate and disagree with you there, plants in a low tech tank can bottom out CO2 within the water. 3ppm will quickly be eaten up by plants faster than it is re-absorbed from the atmosphere.
