One by one shrimp dying

So I have a 10-gallon tank that's been set up for over six months.
Lately, I've been having one cherry shrimp die a night for the last 5 ish nights.
My tank is planted, Fluval stratum and usually it kept my ph around 6.4 but lately my ph is testing around 5. GH is around 75 ppm, Kh at 0 (because of the substrate)
No nitrites, almost no nitrates, and 0.3 ammonia. I run low co2 to keep the plants growing 1 bubble every 4/5 seconds.

I am not sure if it's the ph and slight ammonia that's now showing up, that's slowly killing the shrimp. But I had them in the tank for weeks before this started happening.

Is there anything I can do to save the rest of the shrimp from dying off one by one? I have tried to investigate why they're dying off and haven't come up with anything.

I have another tank that runs the same in a 5 gallon and haven't had any losses of yellow neocardina's that I have. The only difference between the two tanks is which plants are stocked.

CO2 is on a solenoid so it's not leaking at night I have double-checked that a few times. Plus it was unplugged last night, and I still had one dead this morning.
Temps are constantly 74-76.
I don't add any extra oxygen at night. I have a spray bar in the tank that I use to get good surface agitation.
