I don't think there are any health concerns really. Its about the quality of smoke.
Have you ever smoked weed in a joint that snap crackled and popped? The doob would constantly run? or burn up the side?
That is weed that isn't flushed properly. Not to mention the taste. You can taste the nutes. even if you cure for months its still there.
If you grow outside in the dirt without adding nutes there is no need to flush.
When you grow indoors, with a small amount of soil and add nutes then you do need to remove as much as you can in the end.
In hydro yes. There is no soil. You absolutely do need to flush or else...
