Browning pistils AG Kush (finishing early?)

So my Afghan Kush Ryder is exactly 7 weeks old today (49 days from planting) and I had planned to harvest on 69 days so in theory it has another 20 days to go.

However it looks like about 60/70% of the pistils are browned/orange and is visibly browning from a distance. I have looked at the trichomes with my loupe and a lot of them seem cloudy, with some still perfectly clear and sparkling but no obvious amber yet.

Is this normal? Perhaps the pistils will stay as they are now and it will just fatten/amber up over the next 3 weeks, but this is my first grow so any input would be great =)

Cheers.

My input would be try to post pics and should your thread become inundated with responses become good at discerning the trash from the grass!

Some strains can finish early (particularly autos) ..... due to the growing conditions. Take a sample, compare with another sample every few days to find YOUR preference. Pics. would be helpful because some things like (too intense light, over fertilizing) can cause the hairs to brown/orange early.
