Hi-

I've read lots about these plants getting frost damage, but all of my Agave attenuata developed large pale, thin patches on lower/exposed leaves last Saturday, when we had the first very hot day of the year (it was about 90 and very sunny at my house). These plants should be *fine* in that weather, right? Can you help me identify what caused the damage from this picture?

Thanks in advance-
