Depending on the size of the quadrant in your game, it's likely they've plateaued in terms of colonies. The next patch will at least help they turn over facilities on their colonies to improve production, including optimizing breathable populations to undome planets. I'm also pushing ahead other colonization techs to help keep them growing in the early mid-game.

I'm pushing more Mine Sweepers for them, particularly in terms of them being available in fleets.
