Determinar fecha de Floración

Found this answer for you hope it helps: HOW TO PROPERLY COUNT YOUR FLOWERING DAYS Many growers start counting the days of the flowering cycle when they bring their lights down to 12/12. However, the plants haven’t actually started flowering at this time. Instead, they are just entering the pre-flowering phase. You should start counting your flowering days from the day you see the first pistils emerge on your plants. Again, this can vary from plant to plant, so you should check on them daily once you initiate the change in light cycle. The minute you see a pistil, you can start counting down the days to harvest. A NOTE ON FLOWERING TIMES Remember: any flowering information you get from a breeder should be taken with a grain of salt. Flowering times always vary, and you should never harvest your plants after 58 days just because the breeder said so. Always make sure to closely look at your plant's buds and check their trichomes with a magnifying glass to ensure you harvest at the right time.
