However, you could just manually remove them from the plant.
The thing is that every strain has slightly different pre-flowers. Many of the Tanzanian Magic's I've grown had tubular female pre-plowers, instead of pear shaped ones. You could only tell from the hairs. The Maroc I grew this year had female pre-flowers on stems like male pre-flowers.
The strange thing is they're yellow. I'm pretty sure this is a herm, but I'm just going to keep rocking it and if it keeps throwing these weird pseudo male parts, axe shim.
