You need to verify the rotors are properly nozzled.

Don't have near enough information to suggest an appropriate schedule, but I can say with 100% certainty that irrigating every day at the run time you have indicated is WAY too much.

Last week the net difference between ET and Precip was + 0.33 inches (ET) for NYC. Given the reported soil conditions, you didn't need to irrigate last week at all (6/27 - 7/3). Even if you did, and we assume an effective PR of 0.4 in/hour for those two zones combined, your total runtime for the entire week should have roughly around 30 minutes at best.

Ok, checked the nozzles, they're all #7.
What would you recommend my next course of action?

Nozzle them correctly if they aren't. What are the arcs for each rotor?

All 180', with the exception of the corner ones which are appx. 90' due to a swing set jutting out.

Then they are nozzled incorrectly. If we assume 50 PSI nozzle pressure you should be using a #4 red in the corners assuming a sprinkler spacing of 34' or less. You really need to draw a map showing the sprinkler locations and arcs, spacing, and nozzle pressure in order to nozzle it correctly.
