Flowering under 20hrs light but its not autoflowering?

I Planted a bag seed i got in early November and left it outside for weeks and it grew super slow for 6 weeks or so,it was really stunted because the cold, i eventually put it in my grow space with my autos. over weeks it grew slow still then exploded with growth now its freaking flowering for real 'not preflowering' under 20hrs light 4hrs dark.its been flowering now for 2 weeks or so,i was thinking it cant be an auto because its been over 2 months. anyone ever hear of something like this?

Well it definitely has some ruderalis genes. This is why I hate auto's they contaminate the gene pool.

Early bird. Like Renfro wrote it definitely has auto/ruderalis genes in it. Good for certain situations outdoors but terrible for indoor growing.

I hate them indoors, had a Grapefruit years back who would partly flower with 18/6. While people loved the taste, the potency was never there. I was happy when she was put down, lol.

A photo period plant that has been grown under its internal flowering clock, can continue to flower before returning to a vegetative state for up to 5 weeks if placed in environment that is beyond its internal flowering clock!

Good point, I have even had a few rare instances where it was impossible to fully reveg a plant even under 24 hour lighting.
