help guess the sex plz

One month old

I can't see any indication from your picks. The tell tale sign for me when determining a female in preflower is the 2 pistils protruding from a calyx. At early stage though, its hard to tell if its just a new node or a male flower...until you see the pistils come out. Sometimes I have to use a magnifying glass because they're so small,

Not yet...

Thank u guys keep up the good work

my guess is it's either male or female. Nah but seriously it's not mature enough to show sex yet. Maybe in 2 weeks if you switch to 12/12 now
