Chinook IPA

I’m brewing the chinook ipa w/ yeast and it has 3-1 oz packages of hop 1 goes in at 60 min. 1/2 package at 10 min. 1:2 package at 1 min. When does the last 1 oz go in

Dry hop after a week

The last ounce is for dry hopping. I dry hop this one about day 14. The fermentation is well over and the beer has begun to clear. I bottle about 7 days later.
