Is she there yet?

First time grower here looking forward to their first time harvest.
amp;nbsp;
Now I don\'t have a magnifier so I am going off the colour ratio of the hairs. From what I have read, a good ratio is about 70/30. 70 being brown and 30 being white, is this correct?
And I know this is just a photo and might be hard to tell but how far off do you think she is ?
