I got a GG#4 Original glue and a Girl Scout Cookie Fast Flower in FFHF Soil in 5 gallon pots in a 2x4 under 2 Vipar Spectra XS1500s
Nice looking grow! It is really hard to tell if they are ready from the pictures…my guess would be a week or 2 based some of the pistils looking like they are just turning brown and they have not dried up and receded into the bud…but this is not an accurate way to decide.
Best is to get a jeweler’s loop or a digital microscope and see what the trichomes look like. You want them to all be cloudy and most like at least some amber ones…the more amber the more couch lock the buzz is.
Pretty plants 
They look close enough to harvest, but it’s all down to tricome color and personal preference, mostly cloudy with some amber for mind focused effects, more amber than cloudy for more body effects. Clearance they clearly need one time lol. Godspeed spoodermen.
They are close but without being able to see trichromes it’s hard to say, I generally like to see them orange hairs and receding into the bud B4 I harvest if I can’t check the trichomes. At least then they should have a touch of amber. Just a rough guestimation.
Stunning grow brother , are they ready ? Nope hehe …Peace .
