Calyx or male?

I am using feminized Tahoe OG seeds and one plant has pistils already. The 2nd plant does not have any yet but I have noticed these on both plants. I also have a white widow and a cheese strain going and those are both clearly male. Thanks for any help!

How many plants do you have going and how many are males?

I have 4 plants going in a Mylar tent. 650 W HPS about 2 weeks since I flipped 12/12. I used feminized seeds and 2 are definetely female. The one Tahoe OG I was worried about already had pistils, the one didn't. I realized after posting (using an iPhone) those pictures were bad. It's hard to post from it with chrome. But anyway the "problem sites j was worried about cleared up. The opened up this morning and they are all beautiful girls. The white widow is the tallest and fullest. I'm so excited to see it in a month or so. The Tahoe OG looks just about the same size and fullness, however the cheese is the most indica dominant and is about 10" shorter then the other 3. I propped it up to get light and make it the same height because the canopy completely engulfed it.

Thank you for getting back to me

pS those pics are from last week, they are even bigger now
