Is oil from an overfertilized plant bad for you?

So my father is (sometimes sadly) a very experimental person and he made a natural fertilizer out of nettle which was too strong and our plant went brown overnight. We picked the buds, hoping they're still usable and made some oil from them. Can it have a bad effect as it would have if we were to smoke the brown buds?
Thank you for your help.

he made a natural fertilizer…im thinking your good

That sucks! Did he do it just because he likes to experiment or because you guys prefer organic vs synthetic? I prefer to grow as organic as possible but I stick with already made organic fertilizers, gaia green for dry and OMRI listed fish fertilizers for liquid. I would suggest going that route vs making your own lol, at least things are already balanced and measured out for you as far as what the dosing should be etc...

Like bam said, because it's natural you're probably OK
