Hey buddy, i had the same problem not to know when to harvest. Look @ my diary week 12. There are some pics of buds and trichomes. On my leaves are amber trichomes to see while on the buds are still everything milky. I keep them 1 week longer in the tent and startet to flush the soil. They will be chopped if i see 20%-30% amber trichomes on the buds.
Look for amber on the bud structure not on the sugar leafs as they begin to mature faster than the buds themselves. other than that i'm with Burmese with a 20-30% amber for the perfect harvest point! Happy growing! 👊
Hey Buddy, You can harvest once the trichomes are 80% milky and 20% amber.At that time, most of the pistils will be in orange colour.Assuming about 8 to 10 weeks once you start flowering.Happy growing...
