Looks like a calyx to me and not a hermie which is perfectly normal. I asked exactly the same question on my last (first) grow. Apparently hermies look more like long banana shaped shoots. The ones on your photos are calyxes like mine were and nothing to worry about. As EzzJay says, they may be underdeveloped at this stage but hard to tell without a detailed diary. I think its safe to say its not a hermie though.
