Hi Patrick,
I'm not aware of this particular hybrid having a sensitivity to sunlight; however I did think of something that might suggest what the problem is.
If you had your plant in a relatively shady place for a while, and then moved it into much brighter light without acclimating it, this may be the cause.
Along the lines of bug treatments that could cause the plant to cook in high levels of sunlight...this is often the case with oil based insecticides such as Malathion and others. If you are using one of these type insecticides, be very careful with sun exposure afterwards.
Good luck.
