Wow... hate to say this-- but you need to check your grow conditions- cuz those seem to all be showing as males!!!
YES_ it is pre-determined in the genetics of the seeds- but 80% or so of all seeds have a recessive Hermaphrodite gene that, if the conditions are "off", will trigger the Male/Hermie gene- and since the male genetics show faster than the female- you "See" the male parts first... many of them, if you do not cull them, will later also get calyx's....
How did you sprout/veg these? What temps/lights/soil/nutes etc... Lets try to get you on track with an all Female grow!!!
