Do you think it's time to harvest them?

If you passed the approx. days you should start to begin checking trichomes with juwelery lupe f.e. use 50x-100x to see it best. Check stigmata on top/middle/bottom buds and not sugar leaves. all should be milky at least - some waiting for 10-20% amber trichs - to say its ready to harves. Check on Youtube - several videos out there.

High bro, she is nice and frosty! There are only 2 ways to tell if a plant is ready for harvest. The first method is the best method by far and this is looking at the trichomes with a x60 pocket microscope. The pocket microscopes are really cheap. And when you zoom in on the trichomes you want 80% of the trichomes to be a milky white colour. This is the ideal time to harvest your cannabis. The second method is a good indicator but less precisely as the first method. This is looking at the pistils (hairs). When 90% from the pistils is brown it is time for harvest. Enjoy your harvest buddy!

It's hard to tell based on the pictures, but most auto Flower strain are 80-100 days, averaging around 87 days. Is there any way to get a very close up picture (macro on phone works) to see the trichomes? Looking for cloudy trichomes with 5% red or so.
