Oh yeah, I'd call that officially an auto'! And further confirmation of this crosses tendencies...
... and now your Crm. Chz did too!
These F1 a/p crosses can be quite the mixed bag it seems... I've been curious about the difference between and auto x photo vs. photo x auto in this regard. Is one pairing more likely to produce more F1 auto's?
In the mix is if a given (fully) photo is considered an early or fast version as is, like many of the cultivars developed in Canada and northern EU, and how much that contributes to the "auto'ing" phenomena. I'd cite Green Poison as a case for this, as a fully photo she's still very fast; the F1FV is 5 weeks and change for blooming when I run her in smaller sized pots...bigger ones, in-ground take a bit longer which follows what we know about root restriction effects....
I have wondered often about how Sweet made their F1FV line, and how they seem to not have this auto'ing tendency. They do have a nice article in their section about the F1FV line, but I'm not convinced they aren't oversimplifying things... They are the marketing pioneers so far as I can recall, they had F1FV's out there first.
Everything I've seen to date makes me conclude that auto'ing isn't a simple recessive allele inheritance all the time, though it certainly can behave like it. More than one mode of expression is out there for sure though. Witness some landrace/heirloom types, mostly equatorial sativas (PNG, S. America, Thai/Asia) that some breeder-preserver growers have had show the rare "auto" show up in the veg tent under 18+ light hrs

I know HighRise/Krk used Lowryder auto's in his crosses back when, and he found that once he did that, even under non-auto selective pressures there would still be auto's showing downstream in F-gens. Once they're in, there's no getting rid of it and eventually somehow the auto genetics dominate... other have not had this "problem", so it's hard to draw conclusions!
