So if you have no amber, then you definitely have at least 2 weeks to go, 3 weeks would be my guess. Good news is she should still pack on a really good amount of weight between now and then. In the last 3 weeks, the first 2 are the most productive for flower swelling. The last week is mostly ripening. You might not notice much for size difference, but she will definitely be adding density. I would say 50-80g depending on bud density.
