Answer 1

maybe you can relabel your factor?

growth_series$series_id <- factor(
     growth_series$series_id, 
     labels=c('treatment 1', 't2', 't3'))

Or if you are still looking for scale_something, it should be scale_colour_hue()

... + scale_colour_hue('my legend', 
   breaks = levels(growth_series$series_id), 
   labels=c('t1', 't2', 't3'))
