white flour and proportions

I recently started feeding my starter all purpose flour instead of whole wheat. I'm still feeding it at 1:1:1 by weight, but the consistency seems quite thinner. Should I give it more flour so that it maintains the older consistency, or is it fine? (With whole wheat flour, the consistency was like biscuit batter, now it is more like muffin batter).

Also, should I keep feeding it 1:1:1? How do I know when/if to change that? I was reading recommendations of 1:2:2 or 1:5:5.

Thanks!
