i agree, doesn't look ready to me. in the last two weeks the buds will swell, putting on a last ditch effort to get pollinated, making new calyxes, you could get close to twice what you have right now if you wait another week or two.
at least get a jeweler's loupe, available for 10-15 bucks on amazon or ebay, most strains, the trichomes will turn milky when they're ripe, and start to turn amber or brown when they go past prime. you want to just start seeing a few ambers anyway, then you know the main mass will be ripe. if you wait till you see more, it usually means a heavier, "couch lock" buzz
