Is my plant ruined?

You can remove them before they open and check every day if there is new balls If not you should be able to grow it without any seeds If balls come back each time you should throw it in order to not pollinate your other girls You should be wary if you keep it

Yes, male flowers. You can try and remove the individal male flowers, but these plants are generally a lost cause as you say. One missed flower that opens and releases pollen has the potential to make 100s of seeds in your other plants.

Yes she has balls if you are growing her in a tent with other plants I personally would remove her 🙏

as long as your plant is producing more actively calyx and pistil this shouldn't be a problem just remove the male flower and you should be oki. just pass your finger on them (preferably before they open up and are mature enough to drop some pollen and unlike calyx they should fall easily few males flowers the first few weeks of flowering is something pretty common and you don't necessarely need to worry about it check my "gorilla cbd" week 5 6 for exemple more than 40 males preflower, not a single seed in the end.

I would remove it if have other plants. Definitely a hermi! If it's only plant I would take them off. It will be way better then swag 😎,and I used to smoke the shit out of that. We all have had this happen my fellow grower.IT SUCKS!!! I have had this happen with bag seeds. Hope u the best my friend.You will be even better next round ,that's a fact!! And remember it might not be your fault,it could be genetics..

Yes definitely hermie I would get rid of it asap
