Ok folks this is probably the number one newby que...

HI @theNoyd! Not so close to me, I see this plant suffered from nutrients toxicity, so I think she will need at least 2 more weeks, maybe 3. Since you're going to have only 1 cola, I would wait for this cola to be perfectly ripe. The best way to tell when your plant is ready for harvest is to grab a jewelry magnifier / hand-held microscope, and take a daily look at the trichomes. The trichomes onto the buds should have changed from thin & clear / transparent to fat & milky / cloudy / opaque. Once you'll get only milky trichomes, the harvest window is open! For an energetic high, harvest before the first amber trichomes appear. For a couch-locking high, you'd rather harvest once 20-30% of the trichomes have turned amber/red, you'll get more CBN/CBD but less THC. Hope this will help, keep us up-to-date and enjoy your harvest 👊
