Looks normal, maybe a little slow for 2 weeks into flower.
BTW — It is a common mistake to confuse male flower "balls" (the unopened male flowers) with single, swollen female flowers found at leaf axils. On many strains, the flowers that were preflowers swell up and have a round shape. (They also can be pollenated and grow a seed.)
A friend of mine cut down a plant weeks early, because he freaked out at the sight of these swollen female flowers.
