Welcome to the forum! I think you have a bit to go before harvest yet. Do you have a jewelers loupe or small usb/bluetooth microscope to look at the trichomes? Once all of those amber pistils are curled back into the bud, you’ll want to check them and see where you stand. This may help.
Welcome to the community. Your flowers look great. Here is a relatively cheap scope I use and it works great. If you can’t hold steady you can get a microphone stand to hold your scope. Congratulations on your grow I’m interested in growing NL myself.
