I had males show less then a week into 12/12, and some females not show until after 2 weeks. I flowered rather early for their size so they took a little longer. My clones started showing actual bud development a week into 12/12, but they are clones so they keep their mother's maturity so they are fully ready. Some strains just take a little longer too.

If stuff doesnt change, I would definitely look into light leaks. And yeah, 20/20/20 is to much nitrogen.
Racerx Reviewed by Racerx 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
