Has anyone else used Canna boost during the flush as per their schedule?

I’m 4 days in and the leaf on my Royal Gorrila has gone almost black in colour.

Sorry no images it’s nighttime in the space.

My Girl Scout Cookies is going purple and there isn’t much change in my Somango, yet.

Frost on my high THC strains looks amazing, the Somango is a summer smoke at only 18% but it smells incredible.
