No Amber ones that I noticed but about 70% of pistils are red and noticed a lot of milky white crystals. Today is day 59 from when pistils first appearedThats a matter of personal preference. Many will say watch the trichs for amber colouring and chop when you have your desired ration of milky/amber trichs.
But.... ive grown a couple strains where the buds finished without amber trichs so....
If the hairs are red and the buds aint gettin bigger then get your axe out....
Thanks manOn average about 2-3 weeks, but is strain(pheno) sensitive, avoid using this to judge.. but like above ...
use the trics color as ur guide, use this pre harvest anxiety as a time to double check everything before harvest and take notes
good luck
