No I don't think they are ready just yet. A lot of those pistils are still white. They can afford to go brown a bit more. When plants are ready they generally display more of an amber colour. There are a lot of threads of people with plants that are ready I would recommend going to check those out to get a feel for what you should be looking out for.
Yeah theres a while left yet mate. I wouldn't even look at em through a loupe at this point.
Just remember the weight is still coming in.
Its all about that swell.
