Toadstool only opening at night lately

[Alexr54]

Not quite sure if this behavior is normal and wait it out or if I should move the leather.
For the past couple weeks it’s only been opening at night during lights out (and with lunar lights).
For about 4 months since I got it as a small frag the leather has been opening fine during the day.
It’s grown a good amount and had looked very healthy.
All the sudden this started happening. Nothing really has changed.

Here are some pics of it at night.
One with flash and one without.

Please enlighten me (no pun intended) :)

It opened up during the day today.
