@chrisandeden, Flex Daily schedules are not recommended for strict watering restrictions. Usually, if you can only water once per week, the Flex Daily will always run on the allowed watering day when temperatures are increasing and rainfall is limited.
I believe you may have confused your lawn and shrub/tree zones. Currently, the zones with the deeper root zones are scheduled to water after the 18th of March
We apologize for any surprises this morning. The system ran as designed (details below). It's important to remember that only the zones with the shorter root zone depths (lawn zones) have been running. Additionally, it appears that the root zones for these zones has been reduced from the target/recommended depth of 9 inches to 7 inches.
Let's review the data available in your moisture graphs:
As of this morning, your zone's allowed depletion was sitting at 9% Forecasted rain totaled .29 inches...
Looking at next week's weather, the ET forecast indicates the forecasted rain of .29 inches wouldn't last until your next allowed watering day (Sunday)...
Taking the current moisture balance as of yesterday (.04) + the forecasted rainfall (.29) and subtracting forecasted daily ET values, your zone's allowed depletion would have been met on Friday if we didn't water today.
Some ideas to extend your waterings moving forward include:
* Change the root zone depth to 9 inches for turf zones
* Increase the allowed depletion to 60-70%
* Decrease the crop efficient to 50-55%

Hope this helps
