Male and female preflowers

[Marimbas]

Hey guys well I have seen some questions about this topic, well this are not like absolute preflowers, BUT this pictures show males, and female flowers, in its first stages.

First this is a female from my actual grow


this is a male from my actual grow


And this is a developed flowers of a hermie i had long time ago



In my opinion this is the earlyest you can tell sex of a plant, this are male PRE-PREFLOWERS! you can hardly see them, and its very hard to be certain, so im betting for a male. but i may be Wrong. Just look in the internode, just beside the branch, and behind the spear, there is a little ball.
