check the op info, 8 weeks in, flushing, breeder says another 15 days to ripe, already has no clear trichs, all cloudy milky, and some amber. I suggest harvesting exactly on the date the breeder has suggested, why wouldnt he?
my conditions are near identical to that of my seed breeders' rooms and voila!! my trichomes most often are milky solid white in the time frame they have given me. I've grown hundreds of cup winning strains and the experience has repeated itself for me. Sorry you are unable to count on the breeder specs. If you buy seeds from a breeder who "throws numbers out there" then you deserve what you get, enjoy it.
