first grow

Judging by the pistils maybe a week or so. Depends what kind of high you're looking for as well. I would reccomend using a jewelers loupe or a microscope to look at the trichromes. More cloudy trichs will lead to more of a head high, where more amber trichs lead to a more couch lock high. You could get the balance in between with milky trichs and a little amber. If judging from pistils I usually would chop around 75-90% browned.

Harvest when 70-90% of the hairs turn red. You can get more accurate checking trichomes with a jeweler's loupe. 10-20% amber trichomes is perfect. Looks like you may have another week or so.

Para cosechar de buena manera debes mirar la maduración de los tricomas con una lupa, saludos.
