Sorry Kingrow1, I have to disagree. You can be diligent in pinching off those sacs, but there's no escaping a Hermie.
True story; breeder's boutique dog fem was a straight up hermi in 99% of cases but if you cloned it the clones were female and super fucking strong.
Infact the reg dog(no hermi) is one of their best strains imo if the smoke is good ill grow it out.
Ive a few cheese atm that I know can go hermi but im going to clone all 3 if they all turn to be fem n run those next round but killing off the lanky one either way(most hermi prone) but ill definitely run the clone next run though.
You should always wait it out with sex, they wont throw pollen till they develop.
When I started I didn't know about pre flower identification n would wait till flip to sex and I noticed a great indicator that helps alot when GUESSING at an early stage is the space between nodes, ive found the tallest with the longest node spacing to be a greater percentage to be male but again this is only to be used as an indicator in conjunction with other mentioned methods like hairs obviously like for when to chop,everyone says oh the trics need to be blah blah well thats alot to play with genetics so I go by 3 indicators for harvest (bud density,trics and receding hairs) for when to chop.
Just like when I invest time== money on veging out plants im gonna be damned well sure im 100% of the sex before I cull just like im gonna be sure its ready to chop when it is...and stuff
