Hi, Friends.. I’m in my first grow with northern Light Fem and GSC Fem. So now they are in week 4 flowering. They are growing in coco coir. So I want to know when should I start flushing and when I prefer 20% amber when I harvesting. This is my first grow please help. Thanks you.
Northern Lights and Girl Scout Cookies are both two excellent strains! You need a 30x-60x LED eye loupe or digital microscope to check your trichomes. I would start checking around the 7-8 week mark just so you can get comfortable checking. its kinda an art (experience helps)
