Switch to bloom nutes?

Continue with grow nutrients until there are small budlets/tufts of pistils. Cannabis still needs adequate nitrogen in early flower and switching to bloom nutrients too early (when the first pistils appear) can lead to issues down the track. A plant isn't really properly flowering while there are only a few early pistils/calyxes, just getting ready to flower. What I have been doing for 25+ years with great results is grow nutrients until the small "budlet" stage, then half grow and half bloom nutrients for the next 2-3 weeks, before changing to straight bloom nutrients through until maturity. This seems to produce the biggest and healthiest flowers on plants that don't exhaust themselves by harvest time and end up a sickly yellow colour and full of dead crumbling leaves. This method was arrived at through a previous 10+ years of refing my techniques and after using this method for the last 25+ years I swear this method will give you the best results possible. Hope this helps, Organoman.
