Spotting Males Before Flip

Around week four or five of veg, regular indica plants show pre flowers at the nodes, and that is the moment to sort them rather than waiting for the flip. Males form round balls on a short stalk, while females show a pointed calyx with a white hair, though the first few can be ambiguous. Close up photos of both at several stages are posted on https://kushindicaseeds.com, and a cheap jeweller loupe makes the call easier. Pulling males late means pollen everywhere, so check every few days.
