The secret is in your trichomes! They will tell you when your plant has reached maturity and is ready for harvest. Keep a microscope or a jewelers loop handy. If your trichomes are clear, it is too early to pick. When they start to turn milky white you are close. Wait until you can see a slightly amber colored liquid in about one-third of the trichomes and then you are ready for harvest. But donā??t be afraid to let it go another week or two from that point.

Hope this helps...
