If its at 38%ABV now try upping it to 43-45%ABV.

Calcium is used to buffer up

A few drops of the strip perhaps? Probably wouldn’t take much, possibly not noticed before filling with product.
Why do you have to temper to 38%?

If your pH is alkaline you have excess of OH-. OH- likes to join up and form complexes with other 'stuff' and precipitate out.
Lower the abv the more likely it'll precipitate out.
So any ions in there, could be calcium in the water (could be any range of minerals as OH isn't that fussy) but who knows, will stick to the OH- and precipitate out.
Off to bed! Peace out!

And it will given time, there will be a white film/powder on the bottom of the bottle and if shaken it will go cloudy again.
