If you have a plant that has "balls" (pollen sacs) that open at the bottom to reveal tiny yellow flowers and a small banana-looking thing, it's either a male or a hermaphrodite.
Males don't grow buds. Herm's grow some buds but they're mega-seedy and generally worthless
Plus they pollinate pure females, which means a loss of smokable yield.
If both of your plants have flowers, they're both boys (or herm's), sorry. You can smoke the leaves for a low-grade high, or make low-grade hash, or cook with them.
If only 1 has flowers, get it away from the plant that doesn't.
I always recommend that people grow at least 3 plants, to increase the chances of getting a girl.
Stress (poor growing conditions) can cause a female plant to turn into a herm. or even switch completely over to a male.
For a female, harvest when 75% ofthe bud hairs have switched from clear/milky to red/brown.
Males are "ripest" right after peak flower production.
