Beautiful but cannot balance

So, I started with TFP pools this year and my pool has never been more beautiful and easy to maintain.
I recently was away for a few days and upon returning, I had a little algae forming at the bottom of my pool.
The water is not cloudy and is still blue but I decided to SLAM to kill the algae.
My FC and pH fluctuate dramatically and I cannot seem to get it re-balanced.
I would like get it balanced so I can winterize and close the pool within the next month.
Please advise.
