Well, two points of view of the same thing.
Lack of water due to underwatering and/or high evapotranspiration due to too much heat/light.

If the problem was too much light then I'd expect the leaves to either have a bit more of a yellow hue to them or else show signs of light damage. I see neither in these photos.
