Vassal Son Cant Recruit?

[Lucerys]

I made my son a lord.

Its been over a week of game time and he is still just (1) in his party. Has recruited no one. The garrison of his fief hasnt increased either.

I am wondering if the issue is that our culture is Crownlands since I choose Valyrian at the start. I can only recruit from inns. The AI is maybe not finding any crownlands to recruit since there is no Danerys or Aegon holdings and no actual Crownlands faction?
