Woowwww, lookin' good! I've got a BB that's stretchin like your gal there. Are you planning on potting up yet before you get too far into flowering? I think she might benefit from a 4-5 G. Is that a 1 gallon?

edit: Yeah, that third pic makes it clear you need to get some bigger containers! The general rule of thumb is 1 gallon of container space to 1 foot of plant height.

Remember, more root mass = more buds
