in big bud im curious too...

and they should get more then 2-3 hours of direct sunlight in my opinion.. I might be wrong.. but I would try to find it more light.. at least 6-8 hours of light.
what kind of ferts are you using?
annd you should think about repotting them.. i've counted like 6 of them all in that same pot.. as another plant
and when ya do repot them go a couple inches up your stem from where their potted in there now.. so they'll have more stability
hope that sorta helps you out
