Are these male or female?? (pre-flower close up shots)

[Hazemaster]

I am pretty sure 2 is male, I think 3 is male also and 1 is female. Which ones flowered first?

Plant 2 & 3 flowered first, and I know males usualy do so. I'm growin 2 strains, the indicas I have showed female pre-flowers first. The sativa I am growing showed signs of sex much later, like the pics above. The indicas have long pistils on most of them, but it's really hard to tell with the sativas.

Above pics are Matanuska Thunderfuck. Do sativas usualy show sex later than indicas? THANKS!
