Hello, I am just heading into week 5 of flower today. I am growing Ethos’ Skunk Hero, photoperiod (8-9 week is what they project for harvest).
Is it normal to start seeing the pistils change from white to orange at week 5? Every other data point alludes the plant is healthy. Very frosty and no discoloration of leaves. I am a newbie and I appreciate the advice in advance! Using Athena Blended.
5 weeks from flip or from actual flower?
In general it seems normal. Some turn earlier, some later.
Unusual changes here and there can be caused by damage, touching it, high wind, or pollination.
Posting a pic might help 
I have 2 northern lights in the tent. One has had all the pistils turn brown last week and the other has very few brown pistils. Each plant is different. Its week 7 and one looks done and the other not.
Looking normal to me buddy! Nice job
Looks perfectly normal to me too.
Absolutely normal Absolutely beautiful
