About to preflower?

Im starting to get these buldges where im lookin for preflowers (hopefully you can make somthing out from the pic)....does that mean the plant is almost mature and ready to flower? or is this a normal thing for all plants? ive been in veg stage for a little over a month now and it has started growing its 6th node.
Thanks for the help in advance

btw i know the leaf things on the side of the steam are in both male and female plants and dont show sign of sex....the buldge is right in between them

anyone have any ideas??
