My plants are at day 21 from flipping to 12/12. There are not really buds yet, just tight clusters of leaves and white pistols are showing on many of the lower flowering sites. So here's my question: When folks state the days they are into flowering, is that from the first signs of pistols OR from when they changed the photo period to 12/ 12? A quick image search of other growers plants at day 21 appear to be 2 weeks further along that mine are showing now. This is my 2nd grow and I remember wondering this last time too. I recall it taking two full weeks to see any signs of flowering last run too (w/ different strains). Am I at day 21 or day 7?
