Ok my GG4 is in 61 days of flowering. Looking thru my loupe there are no amber or cloudy trichomes on my buds. FYI this is a outdoor grow in 20 gallon pots. My leaves are staring to turn yellow but the buds are big and really dense. This plants was planted May 1st and I live in Charlotte, n.c. Should I wait a little longer.
Are the pistils turning brown yet? If so how much?
You’re looking for 85% before you start looking at trichomes.
Nice looking plant. Like @Covertgrower said pistils first, then trichs.
I would say just about all pistils are brown.
just about all pistils are brown now.
If all pistils are brown, then I would say you can chop at any time. This is only from your description, not judgment from photos.
Can you get a picture of an upper bud? (Is you ladder tall enough?) 
Looks definitely ready to me.
this is my first, I have a Girl Scout sitting right next to this one but she is a late arrival and all her pistils are still white, but she is so more sticky and smells like a pine tree. Thanks for the advice.
She looks to me like she is ready from that picture.
That’s a freaking monster btw! Happy growing!!!
Mine ain’t ready on the gulf coast. I’m gonna let it ride to about third week of October
mine is just a feminized but let me tell you she is 8’ tall. I planted it May 1st and she is nasty sticky, more sticky than the gorilla glue but she’s got a couple more weeks and this plant does not have no yellow leaves at all. smells like a pine cone.
Wow man that is an awesome beauty keep up the great work✌️
