Automatic Yard Sprinkler System

Hi fellow blynkers!
Thanks to @Costas code in this post, I’ve put together this:
Blynk App Demo
top part down to button Zone 5 OFF is output control, below Zone5 button is feedback telling you whether or not the zone actually turned on.
Code:

/////////************* **********/////////
//          Blynk Assignments           //
/////////************* **********/////////
/*
V0   - Mode Switch
VX   - Status LED :: Not working correctly, won't switch colors with app closed
V1X  - Manual Switch
V2X  - Auto Switch :: Time Input Channel
V3X  - Actual Valve State
V4X  - Channel Start Seconds
V5X  - Channel Stop Seconds
V90  - Blynk App Notifications Enable/Disable
V100 - Controller Status
V101 - NowSeconds
V102 - Mode on Controller 1=OFF 2=Manual 3=Auto
V103 - NotifyStatus : for debugging will delete
V105 - WiFi Signal Strength

Only trouble I’m having is led colors will not update when zones automaticlly turn on and blynk app is closed. More details here. I wonder if it’s not possible to Blynk.setProperty(V1, “color”, BLUE); inside blynk function?
