Plz Help! Adjusting PH in soil with 2 month old plants

I did not have a ph soil pen when I originally mixed my soil for my 3 gallon pots. If i had, I would have added some lime to buffer the ph closer to 7.0. Now that the plants are close to 2 months old and I have a soil PH probe I now know that my soil ph is 5.7. I have been using biocanna nutes in a resovoir and I have PH up and PH down. I also have a bag of calcium carbonate. The last time I watered i adjusted the PH in the rez to 7.1 hoping it would raise the ph of my soil a bit. It did not.(not even a little) I'm thinking next time I water to raise the ph in the rez extra high to like 9.0 or 10.0 hoping to raise the ph in my soil. Is this a good idea or no? I am also thinking of adding a bunch of the powdered calcium carbonate to the rez and watering with that. Is that a good idea? If so how much should I use? A tablespoon per gallon of water? Any help would be greatly appreciated.

It is normal for "actual" soil to buffer the PH, which means it lowers when wet and raises as it dries

Personally I have never seen a PH soil meter that was worth anything, perhaps you found a new one, but I doubt it

are your plants suffering ?

If I'm trying to raise my PH should I never adjust over 7.0 in the rez and hope that it slowly raises Or should I raise the PH to 9.0 or 10.0 to give it fast bump into the PH range I want it?

a ph of 10 will kill plants fast, your describing things I would not ever consider, so I'll let others answer

Well, I'm not trying to feed the plants with a PH of 10.0 just trying to raise PH chemistry of the soil quickly

you are going to kill your plants fucking with ph like that... feed at a reasnable ph 6.5-7.0 range and let the soil do its job.
