Outdoor autoflowering grow

Kinda cold weather, though the buds will turn purple, coldest nigh was like 9°C.I'm going to harvest 24h after stalk splitting. The plant in ground must have very deep roots because the flush don't look that successful. Even though it's the same strain that has 11and half weeks, I'm going to give her 13 week, I'd like to harvest 30%-50% amber trichomes so it would be more "couch lock" high.
