One Zone Pressure is Low

I have a 5 zone system but one zone has low pressure. Howevery half of the sprinkers seem to work fine in the zone, the other half dont have enough pressure to raise the sprinker head.

I manually turned on the value and the problem persists. I replaced the sprinkler heads but the problem is still there.

Is this likely a broken pipe or leak somewhere? I dont see any wet spots.

What is my best way to find the leak?

Either the valve isn't coming on all the way or there's a leak.
If you have poly pipes then maybe the line's pinched somewhere between where the one heads working and the next one's not.
You can turn the nozzle off to each sprinkler head then turn the valve back on to force a leak to show itself.
