Both some males and females flower so yup this is an hermie.
It's not rare the first few week of flowering to have a few male flowers when the plant is already producing actively calyx and pistil on all apex. In most lite hermie case you just need to remove the few male flowers preferably before they are mature enough to drop some pollen and you will be oki and still get a harvest without any seed.
you can have a look at my "gorilla CBD" week 5 & 6, i had more than 40 males flowers the first 3 weeks of flowering then it stopped afterward.
Happy growing
