Sure should have amber trichs by mid oct. Nice plants! What's the strain?
they look further along , i think they should finish......... but the last pick , where the line from the sun ends horizontally across the picture, you have bud rot there. DEF need to check the larger colas...

You're better off cutting the plant now. Once the plant gets the rot it won't be long before the rest of the buds follow suit and gets the rot too. It's not worth the risk, imo. You have be in a really wet and humid climate to have bud rot fairly early.
It will be better than finding bud rot hidden inside big colas. Many times you can't see it growing inside the fat buds. If you want to stretch it give it another week and chop it. Just a recommendation obviously but take it for what it's worth from somebody who's been there. At least cut the colas and let the little pop corns buds keep growing. One fall, I've saw a fairly healthy plant turn to complete mold within one week.
