I'm on day 30 of flower of what the packet says is a 45 day flowering time from when flowering "commences". These are Blueberry Muffin from Humboldt Seed co.
The reason I care is that this is my first run with them and I want to use Winter Frost which is supposed to be used 2 weeks before harvest. Are there any clues my girls will give telling me we are in the home stretch and to begin using the product?

@Mednugs If you have a microscope or a phone that can zoom in enough then you can see the color of the trichomes to get an idea of how they are turning. That plus looking at the color of the pistils.
