Thanks for commenting and having done some research I'm now almost certain they're just calyx's growing as I can see pistil hair coming out of them.Pics are properly poor quality, but they look like the swollen calyx that you get at the junction where the nodes meet the stem of the plant, and where the plant first shows sex.
Therefore female and normal??
At 9 weeks I'd just continue the grow mate, you're going to be chopping in the next few weeks anyway.
