Very very normal! Even once I asked the question got my answer (calyx's) I was so smoked out one day I asked the SAME freaking thing like a month later on another plant...

(thankfully AFN is forgiving) felt like such a heel.
A calyx is nothing more than a pod for a seed. Take one of the sacs in question and pop it open? If empty inside than your good! Saw nothing in those pics that would indicate a Hermie,(if you look at the sacs you'll see pistils coming out) just looks like one sac is questionable to me....
Only been growing for a year, so hopefully someone with more experience will pipe in.
