I have 10 Mango Haze flowering now at day 51 of flowering. They technically have been flowering for about 75-81 days, as I had major problems at the beginning of flower. Bud formation aborted due to a nutrient deficiency, but once I improved their diet, they took off, and have actually been flowering for 51 days.
I have one that looks like she'll be ready in a week, but likely needs two. Only about 20% Cloudy Trichomes. About 20% white pistils at this point. Among the densest buds among my ladies, but smallest buds out of the group, but she makes up for it with a truly unique smell. Smells like a bag of Christmas hard candies. The mixed assortment you can buy. None of the siblings share the scent with her, while I have about two other distinct scent profiles among the rest. So Its looking like a little over 9 weeks for her. Im sure I can shave a week off her flowering time in future iterations.
The rest of the plants will need 2-4 weeks. An average flowering time of a little over 11 weeks.
