larger?

in my honest opinion, yes they will continue to grow for a while yet. Wait to harvest at least the 1-2 week as @gmslave says, and as recommended for mimosa evo from Barney's farm (65 day + of flowering). @The8thChevron the GreenArtisan's plants are clones of mine, I know for sure that the stigmas are oxidated practically a week after appearing, this pheno is like that, but looking at trichomes they are all still perfectly white. Plus she is really very haze and usually this kind of plants should have a quite slow flowering. Anyway this is only my opinion, I asked GreenArtisan to make this question to let people more experienced than us to clarify the ideas but I wanted to point out stigmas don't really count, at least in this case.

Probably not. The hairs have all turned which means it's no longer creating new flowers. What you have now is what you'll have at harvest. Don't worry too much though, density is way more important than size.

No, she is well and truly ready for harvest. Any much longer and she will be losing THC faster than you can say Jiminy Crickets. Her metabolism would be almost stopped by now, meaning THC is breaking down into CBD and CBN, faster than it is being replaced. I have been keen to try this strain, but never quite sure if I should add it to my line up, however, after seeing your pictures and how beautiful this plant looks, I think I will most definitely be placing an order very soon indeed! Hope this helps,......... Organoman.
