Week 3 day 5 of flowering and I'm seeing amber pistils?

Hi, so like title says i'm seeing a few amber pistils on one of my plants. I'm growing Northern Lights #5 from Nirvana and it says it has a 6-7 week flower period so i'm just wondering if this is normal. Buds aren't very big yet because i'm only just getting to week 4 in a few days. I guess if this is any indication I should harvest around week 6? Probably flush 2-3 times after week 5 hits right before harvest.

you forgot the picture so we could see what you are looking at

it would help a lot.

i would wait its always better

The pistils will start to darken progressively. You don't just wake up and they are all changed from white to orange/yellow, and your plant is mature. The pistils will die off after they lose viability, and the calyx that sprouted them gives way to new flowering.

I am guessing that it is just the beginning of the maturation of your flowers, as you are past/near the half way point.

Pics help though

I wouldn't go worrying about the harvest just yet....it's still a little ways away.

EDIT: Another thing to consider is that you touched the flowers and hairs on that plant with dirty or oily hands. I have seen that happen.
