Looks good I assume this is your first "real grow" cuz it looks like you have a good setup. That or you took your time reading an preparing. The plants look perfect, granted some of those buds are small they look dense and plentiful. I love the look of those nugs, frosty and healthy. Plus you still have 3 weeks +/- and you will get a ton of bulk yet making some beautiful and bountiful colas.Looks like you have it down but I just want to mention pumping them full of bonemeal is a great way to add flower mass and great taste, I really use a ton of it alonge with a carb/sweet and that's about it for the last 2 weeks for massive great tasting nugs.
What strain are you running?
