I hope I did not make a huge mistake (Fungus related) PLEASE HELP

I posted this in the indoor section and it should have been here SORRY !

Hey guys, I had some fungus on one of my plant and used a sulphur-based fungicide on the bud to control the outbreak. I got scared and splayed all my flowering plants.

I just realized by reading about the subject that I should not have used a fungicide on a flowering plant.

This is the product I used: Safer's Defender Garden Fungicide: 16 oz. Concentrate

Do you think it could be dangerous for my babyâ??s or for me if I smoke it as they are almost ready for harvest ?

Thanks in advance.
