Its a male preflower...they pop out to seduce your ladies earlyalso the light cycle hasent been changed yet, there still in veg 24/24
You chopped it? spewin mate. one of my plants pre-flowers looked IDENTICAL to that and she turned out to produce some potent fucking buds.... don't always listen to what everyone says, sometimes you just need to find out yourself.. it wouldn't of hurt to go an extra week to find out if pistils came out or not, as mine did.. and as i'm looking through the replies even respected members are telling you a mouthful of lies. i can GURANTEE you from hands on experience and a plant that looked IDENTICAL that they are not male pre flowers. if anything they look more like female pre flowers just un-opened calyx's. i really do feel sorry for you as very good chances are that was a female..
and if any that are still mind-set that they are male pre-flowers i have picture proof of pre-flowers that look more nut-sacky then his yet they still turned out to be female calyx's. I have pictures of the pre-flowers and pictures of them during flowering..
