From what I see in your picture:
The pistils (hairs) are long, thin, and turning reddish/brown in places. This can be a sign of cold temperatures especially during night time or too intense light/high temp during the day.
The calyces (the small pods at the base of the pistils) don’t look swollen like they would if they were filled with seeds.
I don’t see obvious signs of seeds forming (pollination usually makes the calyces rounder and you can sometimes see the outline of developing seeds).
For landrace sativas, it’s normal for them to take much longer to mature compared to modern hybrids. At day 60, many pure or near-pure sativas are still in mid-flower, with pistils cycling through white to amber/red as the plant continues building buds. It’s common for them to "throw" lots of new hairs over time.
Signs of pollination you’d watch for:
Rapid browning and receding pistils.
Noticeably swollen calyces with seed development.
Less resin production and energy going into seed growth instead of flowers.
Based on your photo, this looks more like normal sativa flowering behavior than pollination. At this point (day 60), especially with a landrace-type sativa, you’re still in the early to middle flowering phase, and it could easily go 14–20 weeks total.
I hope that helped 😘
