m0useanswered grow question 8 months ago I don't any reproductive parts indicating its sex or if its a hermi plant in the photo your provided.
All plants can turn hermi, it just depends how much stress causes it to go hermi.
Small normal stressors like LST or HST should not cause the plants to go hermi, and if it does then its bad genetics that is not locked in well or diluted/interbreed with garbage.
I don't know what you classify as extreme heat but anything below 28 is ideal. 29-32 hot and 34-40 is extreme to me. just keep your environmentals in check and you should be ok.
Good Luck!
