Is my Phal straining herself to death? :(

[Shikitita]

Hi,

I wasn't sure if this was the right place to write my post or not, so if it needs to be moved somewhere else, plesae do.

Basically I've had a Phal I bought nearly 6 weeks ago together with another one. I decided to repot them straight away, as the plastic pots they were in had the roots touching the base straight away, and nothing to elevate them from the gravel they have inside the glass/ceramic pots. (It's too dry where I live and they don't have enough humidity.)

Both of them were blooming at the time, but for some reason one's dealt with the repotting perfectly whereas the other one has gone weaker and weaker...

Now she still has 5 buds left of which she's trying to open 4 at the same time, but it's taking her ages lately and they don't open completely till around 7 days after they started. Her leaves have wilted (I'm not overwatering her, I swear) and are now "deflated", some of the flowers (the eldest ones) have lost their strength and the top petals are now bent; and she still has two small stems trying to grow plus one trying to come out (all in the pictures).

I am not sure if it's being too much work for her and all the energy she's putting in the flowers, which doesn't seem to be enough, affects the leaves by being wilted and weak.

Is there anything I can do? I don't wanna cut the spikes with the flowers so she can focus on the leaves (not sure if that'd help), but at the same time it worries me that she's straining herself so much she ends up dying.

Any advice will be very welcome.


P.S.: The pictures are a progression from when I bought her, the pink one inside the black pot in the first picture, until today (excuse my bf in one of them).
