Sorry to leave you hanging WVR..
There is a pheno that comes out in Auto/photo crosses...it is like Auto in that it will Flower under 18/6..and 20/4..
but..
it does not "SET" bud..just sits with the Fangs your girl has and keeps on vegging...
I'm not sure if Your girl is a slow Auto..like Stones JEM..or one of these inbetweenies...
What light pattern did you have her on..?
I'm pleased your system is big enough to cope with her..
