Yeah - your camera's ok... COULD be closer but it's ok when I zoom in... But you're right, no amber showing yet although I wouldn't worry.... you probably have at least 2 more weeks to go. You want to see amber on the buds themselves - trichomes on the leaves will show amber before they appear on the buds but it's the BUDS that are important. When you harvest will depend on what you want for your smoke .... if the trichs are all milky, you will get a head high only... if you wait until 10-20% are amber, you'll get a nice combo of head and body effects.... if you wait longer, you'll be getting into couchlock territory. If you wait until more than 50% are amber, the THC will start to degrade and the quality will be going down...
Good luck!
