Can someone help please

Hi everyone, i'm very new to this site and new to growing and love to learn along the way and i have some questions. I have a strain called K2 that is growing and have done alot of research before growing took place and using a aeroponic/bubbleponic system with foxfarm nutes. One of my questions is on one of the plants there is 1 teardrop looking pod on each side of the nodes about 5 nodes up from the bottom, so what im am wondering is are these female flowers or male flowers. Everywhere else i have read the male flowers are a bunch of balls that look like "grapes", but what i have is only one on each side instead of "grapes". So i was wondering if anyone could tell me what they are? The plants have been in flowering for about 5 weeks now and have pistils all over them so as far as i can tell they are female but the 2 teardrop balls are what worries me so im hoping they are just calyxes. Thanks for any help you can give me
