"feminized" seeds doesn't necessarily mean you will get all females. the conditions that the plant is in will be the determining factor in most cases. if the plant is heat stressed or have a nute defficiency there is a lot greater chance of it being male. i bought 5 feminized LR2 seeds and got 4 females and 1 male.

yeah id say your plant is def a female by the pistil development by the calyx (sp?) although it can become a hermie. either way you will have buds.
