Definitely don't toss it!
In years past when we'd have an early spring, I've put my kids outside earlier than norm, only to have them stop growing- just stop. Then, they take on a flowering stage appearance because of the light cycle still being short. Sometimes they'll show enough to easily sex them, thus allowing me to remove any visible males.
As the light cycle increases, they will return to a vegetative state after a couple/few weeks, and grow pretty normal troughout the rest of their life cycle. This can stunt them a little bit, and it can increase the likelyhood of hermies. Just have to keep an eye on them when they flower.
This has been my personnal experience with "early bloomers".
Good Luck
