You got a bit of fox tailing going on, so it is definitely stressed. Most of the trichomes look cloudy so I'd say you're in the harvest window. Whether you want to wait additional days for the trichomes to turn amber is totally up to personal preference. I tend to grow more Indica heavy varieties, so I don't mind taking things down when everything is about 90% cloudy and 10% amber, since the types are already "couch locky" and don't need the additional time to create the sedative effect.
My usual advice is invest in a microscope! Not a jewelers' loupe. A good Celestron microscope with a 100x optic and better. That will definitively answer almost all your questions about trichomes and pests. If you're serious about growing and do it often it is invaluable in your toolbox as a gardener.
