Yellowing on flower sheath of Paphiopedilum

[SillyKeiki]

We have been living in constant heatwaves. With 34-39°C and 30% relative humidity outside, although I managed to keep a maximum of 29-30°C in my grow space, with an humidity of 60% RH thanks to my cold mist humidifier.

Maybe it was too hot for my Paphio, but there is little I can do as we don't have air conditioning in this flat. We moved here in July.
