Green Crack growth cycles

I started some Green Crack seeds a while back and 9 days into flowering I’m seeing no signs of sex in any of them. Is this unusual ?

If you put her into flower it will take a few weeks for her (or him) to show.


Seriously? Is that just because of the strain? I’ve never seen one take so long

Do I just need to wait them out or are there any tell tell signs of sex early ? I noticed one in particular shot several inches above the rest after putting them into close.
