On the schedule page, you could find the reason of no watering. There are two reasons: 1. skip by sensor moisture, which is set to skip program is moisture is larger than 80% (settings->sensor->water adjustment). 2. skip by weather forecast. The setting is in setting->rain, you have set the threshold to be 0.2 and set the skip days as "Previous day" and "rainy day". According to your setting, Netro skips programs on 17th. You could update your setting if you want.
