grown for years, but never read a lot about it, just used trial and error. quite a few of my grows haven't shown any flowers for over a month after going 12/12. my current crop is only now starting to develop flowers after 6wks of 12/12. They are large plants though, over two metres high at the moment, so don't know if that makes a difference to when the flowers show.
mashedguy Reviewed by mashedguy on . 2weeks into flowering and no flower? It has been 2 weeks and 1 day since I've switched my plants into the flowering phase but so far there has been no sign of flowers. How long does it take after switching to 12/12 that flowers appear? I am still using 20-20-20 fert and is planning to use this throughout the whole process until next crop, is this fert affecting the flowering? Thanks! Rating: 5
