Only 1 of my pool jets functioning

I have Pentair VS pump set at 1800 Rpm’s and have had this as the default for the last 7 years. This year it seems like the first jet is pressurized and working fine but the other 4 are not pushing water unless I increase the speed at the pump 3-400 rpm’s. What could be causing the issue?
 
Assuming all valve positions are the same, decreased pressure at the returns is usually a sign of a dirty filter.

Do you monitor filter pressure? TFP recommends cleaning or backwashing the filter when pressure increases 25% over baseline (clean pressure).

How does the water look? Any cloudiness or signs of algae?
