By now they should be well and truly flowering. Sure they are what you think they are? They seem to be behaving more like "normal" photo dependent plants than auto flowering plants.. Autos normally start flowering around the 3-4 week mark; maybe at 5 weeks at the latest in my experience.
You could try asking Fast Buds, direct to see what they think.
