showing sex

Hey guys! I have a Wedding Cake plant indoors in a 2’x2’x4’ box, HLG 100v2 3000k, ffof/perlite (60/40). About 36,37 days old. Doing great and I’m just wondering if it’s starting to maybe show sex? I noticed an extra little growth on a few tips that doesn’t look like new shoots. Really tiny and...

Does this mean if not kept under12 hrs of light will flower hahaha, to me thats a small calyx with a pistil shlowing.

Hello all, This is my first grow, and I think my plant has shown its sex but its hard to tell. I also am wondering if it is too early to tell the sex of the plant. Below are some pics, any help is greatly appreciated.
