Hop Tea Question

[Amalheiros]

I have an IPA in Primary for 10 days now and am getting ready to transfer to secondary in a few more days.
I understand Introducing a hop tea helps with the beer aroma...But I have a question.
When is the best time to top tea?....Upon transfering to secondary or just before bottling or splitting it up and half at each time?

btw I'll be using real whole cascade hops not pellets
