Sacrificed some flowers for new growth

[l1sav]

Hello all

I have a good size phal 'Diamond King' has 8 leaves and another one growing. 3 spikes and they all have lost a lot of the flowers apart from a few on each spike on the end. No more growth on the spikes for ages and getting ever so leggy so i decided to sacrifice the last remaining flowers on each spike and cut all three spikes down to the next available node.
Was that the right thing to do?? Thought maybe it would encourage some new flower growth off the spikes.

Thanks in advance.
