She looks too young to me at this stage. A jewelers loupe will allow you to check the trichomes, which is best. They are relatively cheap, I think mine cost around $15. Look for milky to amber trichomes, not clear. Without a loupe my best advice would be to wait until about 80% of the white hairs have darkened and curled in. My guess is you still have 2-3 weeks to go. Stay patient, it will pay off in the end!
