To cut or not to cut?

[supermoniQ]

Hi everyone! I have a phal that I acquired 2 months ago and it's been in bloom since. I've lost some buds due to a change in potting medium (previously in tightly packed moss, ugh!!) and only have 2 flowers remaining.
I noticed a new leaf growth (yay!). Should I cut the stem with remaining flowers to give the plant am opportunity to focus on the new growth, or should I just let it be??
I'm a bit confused.

Any info/ feedback is greatly appreciated!
