I would say another 3 to 4 weeks They appear to be just starting to ripen.

But the best way to tell is get a Loupe or strong magnifing glass and look at the trichs ( the white stuff on the leaves and buds ) and check the color. In the beginning they are clear. then turn milky or cloudy, then turn amber in color. Most of us harvest at the first sign of amber.

I have seen a chart on some of the threads in here that were asking the same question and is great for this. Try looking at some of those and also look at some of the grow logs to get a real good idea of when it is best to harvest.

We just can't do it by looking at pictures unless you have a real good macro camera.
