maybe this will help
male plant = bulb,flower,pollen (never kill a male without extracting its pollen and saccing a female to produce f1 seeds. lose 2 gain 100s i say.)
female plant = swelling calyx's,high thc production,pistils increase hoping to catch male polllen (this part here is what we want, horny sex starved females gushing for some pollen)
hermied plant = orignally female genetic start stressed to the point where it forms one or more male parts to secure next generation. nowdays even males converted with chems are considered hermi.
pratice makes perfect. it was fukin awesome to see a male plant explode with pollen the first time i ever grew a male.lol.(given i took it to a freinds house cuz i was scared as fuk it would seeed countless bitches ) its all good experience i think.
