Pool flow issue

Got home today and saw that my pool was green. Chlorinator still had tablets. Vacuum seems to travel up side walls higher and move throughout pool a lot quicker, but water features and return jets have way less flow. Checked pump and saw no air. Filter pressure was a lot higher, so I backwashed the de filter. This helped the filter pressure for awhile, but everything else was unchanged. My flow isn’t making sense to me. Any ideas? Thanks.

Here are two guides that we put together for low pool water pressure and cleaning up a green pool that may assist.
