Hairs can be misleading as stresses can cause new pistols to form (like in foxtailing) regardless of how close to harvest she is. Some strains have pistils that stay white more than others meaning your plant could be ready for harvest and you would not know. Always go by the trichomes, they dont lie. You can adjust the high as well. More sedation you need more amber trichs on bud, less sedation you want less amber trichs. I cant tell from that pics. Get a jewelers loupe or magnifying glass to get a better look
