Pictures 1 and 3 show female pre flowers, I am not sure what picture 4 is all about and picture 2, well??? Don't really know what is going on there, it is either some weird looking male pre flowers or mutated female calyxes growing in random odd places. I have seen buds growing on leaf stems quite often and even on leaves themselves and picture 2 could be female flowers developing on the stems. My diary "Cannabis Conundrums" has pictures of weird female flowers growing on stems and leaves too, maybe have a look at them and see if it looks anything like what you are seeing on yours. If so, no need to worry, if they are just weird calyxes growing in odd places, your plant will flower normally, just with extra bits growing from where they are not supposed to be! Otherwise there are also some pictures of female, male and hermaphroditic pre flowers that may help you identify what you have got going on.
Hope this helps,..... Organoman.
