females showing, how long till big buds?

i have a couple females that are showing sex after two weeks, :D now i'm just wondering how long it should take for the buds to get big?

pics help

they tend to pack on most wait in the last quarter of flowering so at about 6/7 weeks they should start to grow nice n big

depends if theyre sativa or indica's: sativa take from 10-12 weeks indicas should b :6-9 weeks
