This depends on your preference. Do you like to be mental stoned or body stoned. If you harvest earlier (mostly clear/few milky) you'll have a more speedy head high. If you harvest on-time you'll get it when its mostly milky trichomes. This is the best balance of bodyhead highs and is also the longest lasting. If you wait another week, the plant will keep putting on weight but the high will degrade into a more lethargic/couchlock stone(50%+ amber). IMO you should try to get them when the most trichomes are milky. You'll need a microscope to see the little glands.
You can effect the high by when you harvest but it mainly depends on genetics... If you grow a pure sativa it can't be a couchlock stone just like a pure indica won't be a speeedy, trippy high. But you can make a sativa slightly more relaxing by giving it an extra week.
