Correct, the front flowers never runs, even though the back flowers are NOT running because they are affected by weather, in this case prior rain.
Basically, I have all zones set to start at 7:00 AM, even though only one can run at at time. Is this a problem?
When I first set up the schedules, they all ran perfectly in sequence. Zone1, Zone 2, Zone 3 (all lawn zones) running first, followed by back Shrubs, then back Flowers, then Front Flowers.
