Unstable genetics are what bring intersex traits. This is why genomics can be useful in commercial cannabis because you can determine how stable your genetics are before putting seeds out on the market. Some genotypes are more likely to be intersex than others, for example, Cookies strains are famously known for showing intersex traits, but the yield and profile make it worth fighting bad genetics.
Your seeds should pop female, genetically speaking, the seeds are going to have a genotype that matches the mother plant itself. You basically made S1 seeds through stress rather than spraying something like colloidal silver on a branch, however, they're probably not very genetically stable as it seems the mother plant's genes weren't stable in the first place. Stable genes heavily lower the chance of stress-causing intersex traits on a plant, that's why when breeders do pheno hunts, they also consider things that are genotype reliant like resistance to heat stress, pests, etc.
Ultimately, the seeds should be female, but will likely show intersex traits if they are in a less-than-ideal growing environment.
