Flowering?

Monday 4th September 2017 (1836)

My plant has grown very tall and then started changing at the top. I noticed bobbles growing, then it developed into a ball, which then unfolded into lots of small stems in an interesting geometrical shape. It looked like it was going to flower and some very tiny petals started to appear but then seemed to fall off before developing. It has since started oozing sticky liquid from the ends. 

Any ideas/suggestions? Cut this top off or leave it?
