depends, if it turns out that shes an auto that was mislabeled nothing you do is going to stop it from flowering so best to keep it under 18/6 for maximum buddaghe and if not dont sweat it the plant is most likely just displaying pistils because its reached sexual maturity this is called preflowering, nothing to be alarmed about and the plant should continue vegging just fine.
let us know if she keeps flipping.
