Help ! When to harvest ?

[GaGrown]

The plant is 4weeks + into flowering . The light is at 13/11. In a microscope the trichomes look mostly cloudy or about 60/40 but pistil hairs seem still fresh and white. Older leaves and big fans are yellowing and falling off and even turning brown. No nutes . Any ideas??

I'm just curious about the 13/11.. Buds grow in the dark.. More darkness.. Danker Dank! 12/12 schedule,interest you any? Ya outta start movin' the clock back a bit. You'll be happier in the end result.
