Well Irrigation - Pump off but water still flows through system?

Hi all, newbie here that is stumped!

First of all here's my system: I have a well irrigation setup (Florida) with a manual shut-off at the well, goes to a check-valve, then the pump, a ball valve for shut off after the pump, and a 4-zone indexing valve.

The problem: water "seeps" through the system at low pressure when the pump is off, just enough to trickle out of the sprinkler heads at the end of each zone, resulting in a wet yard and sidewalk if I leave the ball valve open. That's great if I want to manually water my yard all the time, just turn the ball valve...but I can't run on the controller automatically, since the water would seep constantly if left open.

I just replaced the check valve with a new one and then swapped the hydraulic shut off valve (after the pump) with a ball valve. I though the check valve might be the problem but the same thing happens after replacement. Could it be the hydraulic shut off valve is still needed after the pump? I looked at a few of my neighbors' systems and they all have a manual ball-valve setup just as I described so am thinking that's not the problem.

My other idea is that there is still enough pressure coming from the well that the check-valve doesn't close all the way, but I'm not sure how to fix that, other than shut the well valve almost all the way off? Could the well-valve be bad?

Hoping some one can help! Thanks!!
