You can grow it, it will likely revert to normal. If it keeps growing sets of 3 leafs rather than 2, then you might end up with super bushy plant. But i also heard that those that continue growing pairs of 3 hermie out easier than normal ones. I had one of those proper 3 leaf pair ones and it hermied very early flowering. Mine started doing sets of 3 after 3rd or 4th node however and looked normal before that. But they are not guaranteed hermies even if they continue doing sets of 3
If you have extra seeds and dont want to risk it, you might just plant a new seed, you are not that far yet.
