I started closing the screw on the nozzles of each head so hopefully a
leak might show up, no luck, then I started pulling the nozzles off a
head and starting the system one by one, I have found a node that shot
water 4 ft high (good pressure) but the next node only bubbled 2"
high. I might have narrowed down the huge pressure drop location..
I'll unearth the between those connections and see what is up.

Does it hurt anything, like the valve or solenoid, to close the
nozzles and pressurize the system like that?

Run it for awhile and follow the pipes, try to feel with your feet any
extra wet area that may be leaking. often a head or pipe can crack at
the base allowing a leak, look for puddling at head bases. Remove the
last few heads and check-look inside for dirt-obstructions, and run the
line to try to clear it, Probably a crack somewhere in the pipe. Yes the
valve could also be bad.
