It is very strange to see such quick drop on pH values.
What you have to keep in mind is that carbonate hardness
(KH) is the one that tells you the buffering capacity of
You can even have higher conductivity values than the ones
you wrote and still have low KH values.
To avoid "up´s and down´s" of your pH values, mantain KH
values above 89ppm (at least).
Hope I was of some help,
