To kill springtails. Thousands of them. I use a watering can with diluted soap and drown them nightly. Today is the first time I’ve noticed the concrete looks speckled/spotty with grayish spots

I don’t know about splotchy spots but I do not have concrete or springtails.
I’ll get some pics. I have more patio than pool. These are everywhere, not from a spill or drops of anything (bleach, ma, etc). I was thinking along the lines I’m breaking down the sealer with the Dawn?

That area must not get full sun as I have the same thing on my bluestone. I'm gonna get the stuff AJ recommends as it is definitely mold or mildew/algae.
Honestly that area is full sun from 11 am til sunset. The patio and pool are on the west side of the house no trees etc. but I’m willing to try most anything 
This is the “big” spot pictured above right now (full sun now) it does have lighter/ darker appearance with light and depending how recently it’s been wet

Any chance the dawn is cleaning some spots and it's getting washed off with rain? Maybe the darker areas are just dirtier than others or maybe the runoff pooled to make larger dark spots? 
That’s a real possibility. I should scrub the entire patio and see what happens.
The first few nights I was a lil heavy handed with the dawn
like a 5 gallon bucket of water with a “squirt” of dawn platinum. There were suds here to Kentucky
But i did hose everything down
