That makes 190 ppm CO2. You are killing your fish. Please note that we are discussing zero KH conditions, not 4 KH. Lower the CO2 ASAP.

Also, will my fish eventually adjust to the lower pH

If they are not high pH fish then yes they will adjust. But they
will not adjust to CO2 over 30 ppm.
The reason why your plants are not pearling is possibly too many hours of light a day or some nutrient deficiency. And plants don’t need to pearl to grow well.
