First grow, in a speaker

So didn’t update last week not much to update on not sure why she’s taking so damn long to get milky trichomes and amber stigmas? Gave her an hour less of light to make the plant think it’s closer to the end of its life cycle hopefully that works and if it does i then plan on leaving the light off for 2 days before harvest maybe on Sunday . I read that leaving the light off before harvest will build more resin from using all the nuts from the roots and leaves to go into the buds. Not sure if it’s gonna work but let’s see , but really can someone please tell me why she’s taking so long to get to peak harvest?
