How are my plants doing?

My first grow what does everyone think?? White hairs started to grow in balls does that me I should be getting buds soon?? They’re autoflower

Yes those white balls of white hair are the beginnings of flowers. Those will grow and swell up into your buds

Thanks do you think I need to get a net or something for support I don’t want to damage plants

How thick is the main stem and branches? Maybe you don’t need one
