it could be a bud site sometimes buds form on the main stem/trunk a the start of the branch. If it looks like like a banana formation it's male but if it's it's leafy it's not! I been looking at it a couple times and it's probably male pollen sacs. Sorry! and in very mature plants sometimes you will find seed "sacs" forming on stems primarely on main stems. If there is no white hairs on your plant it's not good news!
canadianhemperor Reviewed by canadianhemperor on . My plant looks a bit strange, what is this? Right my plant is just over two weeks old and about the first week the two first leafs started twisting a little (not the embryo leafs) , further on the next to leafs started doing the same but not as bad but a lot of people told me that this happens in the first few leafs but i am a bit worried now because a week later it now looks like the next set of leafs are starting to do something strange, looking a bit droopy and i no it has had enough water, does any one no what is happening????
