Pictures of my plants after 3 months of veg, now 2 days into flowering!!

I have 9 big bud plants that have vegged for 3 months and are now 2 days into flowering, they are still not showing any signs of which sex they are, hopefully over the next 7-10 days they will start showing. Every plant is over 18'' inches tall. Any comments appreciated.



p.s. couldn't see how to rotate pics after upload, they were the right way on computer, using a mac though!!!
