Pistils not turning brown

Dont do it! she needs a few more weeks she looks too good to be wasted on a harvest thats too early👍 goodluck "dont judge each day with the harvest you reap, but by the seeds you plant"

Not ready yet, at least another 2-3 weeks to go............your plant "knows" what to do. Once there are 98-99% brown pistils you will be entering the harvest zone.

yup, long time before that is ripe. when the calyxes plump around the hairs and make them look short, then you can start scoping the trichomes to determine your harvest. does look like it needs a bit stronger light too, but outside we can't do much about that. if it gets shaded at various points, move it into the sun.

Simple, then it is not ripe yet. Wait longer.

She is still like 4 weeks away. Either lack of light, lack of good watering or too much nitrogen causes those airy big/ streched /huge buds. They still needs time, browning and shrinking will come. Give time. Watch out for bud rot.
