Can you post some more photos from different angles, especially not so close-in?

I’m not the original owner. Could this blotchiness be from the install of the pebble tec or is it some other stain or accumulation
?

If it were scale, I’d expect to see it on the waterline on tiles. I don’t really see it there.

Bumping thread to see if an expert can chime in. I’m just seeing a nice looking pool.

What leads you to believe it's scale?
What does the surface that you think has scale feel like compared to areas you think aren't scaled?

As @reggiehammond states, it doesn't appear you have any waterline calcium scale buildup. And your test results don't reflect a scaling condition.

When did you notice these areas?
How old is the plaster/pebble surface?

Do those areas feel like sandpaper?

Perhaps ready up on: Efflorescence - Further Reading

But again, I'm not seeing as well from photos.

That is not efflorescence.
