new branch site ?

alright this picture is an example... what are those mini branches and i seem to have something growing at the nodes but my plant is only 3 weeks old... looking good but only has 4 or 5 nodes... and i was wondering if these little green things shooting out are those new branch site forming? or is it the sex already?

Are you pointing at the calyx's? The pointy longer green growth on the front? If so just read up on "marijuana calyxes". But you could be pointing at what will become a male or female preflower

im pointing out the new branch that poped out the middle and has 5 mini leaves notthing about calyxes

Those are preflowers, which can show as early as 3 weeks if they're growing well. Mine always show in the 3-4th week of 18/6, so your's probably are too. Just don't write them off as males yet, as some preflowers are difficult to judge when they're that small.
