Flower or still pre flower

This is the very beginning of flowering, but don't be too eager to switch to bloom nutrients just yet, your plant still needs adequate nitrogen during early flower. I prefer to stay with grow nutrients until there are small budlets/tufts have formed, before switching to a half/half mix of grow and bloom for the following 2-3 weeks and then switching to straight bloom nutrients through until maturity. This seems to produce the biggest flowers and on plants that don't exhaust themselves and end up a sickly yellow colour by harvest time. I have been using this method for 25+ years and swear by its effectiveness. Hope this helps, Organoman.
