milleri - on the verge of sunburn

[rbarata]

Do you think it will handle these light levels?
Full sun from 10:00 to 20:00.
Day temps have been cool for the season, around 25ºC (77 F) with a forecast of an increase to 35ºC (95 F). The humidity not so low, between 40 and 50%.

Night temps around 12ºC (53 F) and HR 90%.

This more or less mimics the habitat but my concern, together with the light levels, is that the plant should have new growths by now.
