i personally don't think they can turn hermie tbh i think they either ARE hermie to begin with. i've fucked around with my plants many times doing lots of stressful shit to them and not once had i had them hermie despite they were all fem seeds. thus imo i think the whole "too much stress can hermie plants" is bs. just my 2cents i don't grow regular seeds. my dad who only grows regs has never had a herm eitherCan a plant turn hermie after it starts flowering or is that worry over?
