If you go for the 9th to stop turning that should be ok. Because if you set on the 22nd the 9th is three days before hatch day but if you set the 25th or 26th it's after the 14th day of incubation. I would not put the humidity up untill you know what is happening with them as a full week of high humidity may not do them any good if they were set on the 25/26th.
