Hello there Nelly,
Well, I have read through the other posts and am concerned that you may not be getting the information needed.
When I face a problem with my plants (of any kind) I like to start from one end of the problem spectrum and work my way to the other end. For instance; Take the most common reasons for an issue and apply them to your situation. If they are not applicable, then move on to the next possible scenario and work through what cannot possibly be the reason. By knowing what is NOT the problem, it becomes more and more easy to determine what can or could be the culprit to your issue/issues. When it comes to budding it is most easy to start with the basic nature of flowering. Light, (or the lack there of) is the triggering mechanism when it comes to flowering most all plants. This may sound easy, and thus is easily shrugged off as a "couldn’t be". As most of you already know, each strain and plant species acts and reacts differently to particular conditions. Each plant will have its own set of circumstances and boundaries of which the grower will have to learn in order to combat issues that negatively effect the growth. If not, the problems will become something that the plant will have to overcome and thus prolong the periods of trouble and stage of which the plant is in. (such as prolonged flowering) I would agree that most folks are correct in that the plant will overcome this and finish flowering at some point. However, there could be a multitude of inter connected/ related issues that happen as a result or simply during that time as a period of opportunity. Hermaphrodism is a plants natural response to stress. This response insures the plants spread of genetics and is a difficult response to reverse if not impossible. If the plants response to stress is to trigger reproduction, you will not only have a longer flowering time, but you will also have a plant that produces male and female flowers which in turn produces buds with seeds.
In the case of prolonged flowering, I would suggest that you consider how many times the flowering room is visited during the "dark hours". If there are visits, the question should then be "is light used to see, and what spectrum is the light?" If there is any light that is on the correct color spectrum for vegetative growth of any kind, there is a chance that those visits are the reason behind the lengthy flowering time. If you determine that your not the culprit (per say), then the next thing that I would check is for light leaks. This can easily be done by waiting in the flowering room while the lights turn off. Give your eyes time to adjust to the dark (say 5 - 10 min) and if you see any light at all, or are able to see period, there is a problem if not THE problem. Then, if there are not apparent leaks, I would suggest searching for items that have lights on them which remain in the flowering room during the dark. (Example: A cable box was sitting next to a plant that was triggered to flower by 12 - 12 lighting cycle. The side of the plant that was facing away from the box began to show signs of female flower, while the opposite side closest to the box remained vegetative and showed no sign of sex at all. This was due to a single small LED "on / off" light that was on the face of the cable box sitting about 3 feet away from the plant.)
If it determined that light is not the issue, I will break down the next possible options to consider however, I wouldn’t even consider them until you have gotten to that point. Rule out the most common problems first....
I do hope that this is of help. I hope that you are able to figure out what the problem is and can add the experience to your bank of cultivation knowledge. If you have more problems and would like to ask me for my opinions, I would be happy to help. Take care and good luck!
