Flowering taking so much

when you say on during the night... do you just mean you run your light cycle at night and dark cycle during day? that's fine, if so. Now, if you switched from night to day and gave more light instead of more uninetrrupted darkness, that could potentially cause a major delay of the intitial hormonal balance shift. (caused by uninterrupted darkness in excess of 10 hours or more.. any interruption can potentially counteract any number of hours less than 10.. fuck up entire balance and therefore vege growth will continue longer than normal or worse.. re-vege occurs if later on..) basically if the light cycle every gets funked up in bloom -- always, always give it extra darkness while getting back on track. while it may not be optimal for growth or bud development, it will guarantee you don't screw up the hormonal balance any further. Seems a while. Some are slower than others. From the looks, i'd wager within ~7 days you'll have the tufts of stigmata at all terminal nodes and it'll be a few more weeks before it expands. This may be a slow plant. The temperature and other environmental factors can impact bud densisty and such, but unlikely extreme enough to stop or delay bloom. if anything stresses should cause it to freak out and try harder to reproduce -- including the trait to self-pollinate. As long as it's not perpetually a problem, again, i wouldn't worry too much.
