Male or too soon to tell?

My plants are four weeks old, growing indoors under a 400w HPS. Two of the seven are starting to show sex (I think).... this is my first grow. So what's your opinion? Male or too soon to tell? Plant #1 (3 nodes pictured) Plant #2

...it's a boy, or at the minimum a hermie.

last pick says it all w/ multiple balls.
