Despite the high temperatures, the Haze XL autos are doing well! They are in the middle of producing their fourth set of leaves. I'm also starting to notice the pistillate hairs that indicate a female plant, so here in a few weeks will we have some bud development. They are starting to produce a bit of smell, just the typical: spicy, herb-y, but the smell is still very mild.
Those Haze seem like they turned out well for you. I'm currently in week 6 of my own Haze XL grow. I ordered my seeds from GC as well. I'm starting week 7 though and still no flower.
