I did a ghusl today where I remembered to wash my mouth about 20-35 minutes the latest and then I went and did that immediately is my ghusl valid?
In Ablution (Wudhu)

If you mean you had not done wudu before starting the ghusl nor you rinsed your mouth and nose and then remembered after 35 minutes and you went and just rinsed your mouth and nose then this is not valid.
You must redo your ghusl.
