What is your water ppms before you do anything to it?
What is the source of the water?

Declorhinated tapwater at 7.8 with ppms of 50 ph down to 6.5 to 6.8 range

At 50 ppms i would guess about a drop of pH down would be enough. Anything under about 100 ppm is difficult to measure and pH down is also just a mild plant food (phosphoric aid) and nothing detrimental about it. Its not going to kill anything unless you really over do it.
How often are you watering?

Yeah i only use a small drop and per instructions of the sohum you don’t flood the soil like you would do with foxfarm nutes so only give half a gallon every other day

Here is what I would do. Next watering before you water check the weight of the pot.
Then water until you get at least a cup of run off. I know with living soil this is not recommended but you need to see what you got. Check the ppms and the pH of the runoff. If its in range pH wise and ppms are 600 to 1000 then it may just be over watered. If something is out of range then you will know what to do.
You wont lose enough nutrients watering with a little runoff one time. Its worth it to know what you have going on.
Take note of how much water it takes to get runoff and then check the weight of the pot again to see if its a lot different.

Great advice from @Spiney_norman and you can always add some beneficial microbes back after the run off sampling

@Spiney_norman has you covered. Get a runoff test done and let us know what you find out! We’re rooting for you… lol no pun intended

@Spiney_norman today I watered enough to get a cup of runoff ph/ppms going in was 6.75/48 and ph/ppms coming out was 7.02/1940 so I should adjust my water in too like 6.3 for couple weeks to bring ph in soil down right

I would and there’s plenty of nutrients in the medium at 1940 PPMs

OG has you covered. Do you remember how much water went in to get that runoff?
If the soil is still wet when you water again it may be the cause of the yellowing and browning of those leaves. Roots need air. The pot will feel very light before it really needs water. It may feel completely empty even.

I am using a 5 gallon fabric pot been feeding about 1/2 gallon of water ever other day when pick pot up was light like felt empty this time gave it 3/4 of a gallon to get a good cup of runoff.

Sound good. Plants just lose lower leaves due to age and its normal.
I would remove any that are browning as they can develop mold on them
Perhaps like OG mentioned you could re-introduce some beneficial bacteria like Recharge or something similar and it will help the living soil.
