Is GF quick to flower?

A customer has a question and I hope we can get some opinions on it, thanks

All of my gold leafs are flowering early, but they are outside and there should be plenty of light here in Central California. The other strains (Chronic Widow, Trainwreck) were germinated at the same time and non of them are flowering. Is GF quick to flower? Do you think they will revert to veg as days will be getting longer for the next month still. Thanks, Bret
