Always go by the trichome color to determine harvest. Use a 40x jewelers loupe to check the trichomes. Most growers will harvest with mostly cloudy/milky with 5% to 30% ambers showing. In a pinch it's usually safe to harvest once a few ambers show up on the calyx but may give you an intense head type high. The more amber the more of the body high you will get. I would put her some where slightly sheltered from the rain until harvest she needs less light during the ripening stage plus she has a nice open/airy growth style so hopefully mildew won't become an issue.👍
