Ok there's another post right here about canoeing leaves, but I didn't want to jack someone's thread. Besides, these leaves look different.

Anyway, here is a picture. There's only one plant that is doing this out of a few.. I think a second one may've shown signs of it. It's not on all of the leaves but on several.

Anyway, what in general are the causes of this? I thought my temps were ok, but I think it may be heat or light because it happened to the plant directly under the lamp (1000W HPS). But the light was never closer than 18" I don't think...
