Outdoor plant still not flowering

A quote from Plagron's website: "Once the days become shorter than 14 hours around the middle of August, your plants start to change. They detect that summer is reaching its end. Time to create a new generation of plants! In the longer nights, plants start to generate flowering hormones, which signal that it’s time to bloom."

I am one week away from full moon. The thing is that last year I had my plant (another Liberty Haze) at the same spot. That's why it would be strange - but still possible - that there was some light leeking. Yesterday I checked it and there is a neighbour with a new house just about 100 meters away, where I can see strong lamps, but this light hits more the Durban Poison than the other 2 plants... Can it be because of that lamp? If it doesn't change I'll put that black screen.

Sativa heavy strains like Liberty Haze can be stubborn/late to flower, but it will flower sooner or later. The Durga Mata, with 90% Indica genes should be well and truly flowering by now, but if you are getting a full moon now, this can be enough light to delay flowering and it should start flowering during the dark nights of the next new moon. The fact your Durban Poison is in its third week of flowering would suggest the plant was triggered into flowering during the last new moon which would correspond to 3-4 weeks ago, assuming of course that you are now in the full moon quarter. Otherwise, the suggestion that there might be "light spill" from an external/artificial source, such as street lamps may be a valid point. If so, erecting some type of screen to ensure your ladies are in as much darkness as possible should get them flowering soon enough, if the moon cycle theory of mine is not valid. Hope this helps, Organoman.

different strains start at different points i always look for fast flowering genetics, that means she starts early for example SHAMAN from dutch passion, she starts beginning /mid of july to flower Or honey cream and speedy chile from RQS, those strains start end of july or beginning of august other strains just start later and take longer to bedone the choice of genetics is in outdoors important Took for " express" or fast flowering Genetics. your plant will start,,,, iam sure you can see tiny preflowers already

Hi @Kukuriq, your doing great dude. If she is a true photoperiod plant the two most probable causes are; 1 - Light leak or light pollution during night/dark hours, this can come from ambient light from your windows or neighbours, distant old style HPS street lights... (an little 8w CFL for +1 hour per day led will stop my outdoort plants flowering if the coverage is full. you can get hermies also) 2 - Locallity and light hours regardless of the time of year. Look on a local meterological website for the timetable of realtime daylight hours in your area. If the plant is still slow then you may have nutrient uptake problems but this would be not usually stop pre flowering and might lead to a poor yield. These are the things I messed up on and I may be very incorrect... Good luck. SMF
