AsNoriuanswered grow question 3 years ago I would give few more days, have few doubts isn't a girlyboy ;)))
Don't rush, I had Northern Light recently she formed only one male sack.
Give her few days and return again or compare to any internet photo, will be a lot more obvious ...
Girls have those single calaxies attached, boys grow them in gangs and hang on small rope.
Good luck !
