Girls, Girl took a little more than a day to respond to me, how long should I wait to respond back?

I sent a girl a text yesterday. I didn't ask her any question in the text, it was a "hey, hope you have a great week" type of text. She only just got back to me over a day later, asking me how my weekend was.

Should I respond tonight or wait until tomorrow?
Tonight. Send her a response before you call it a night
Send something tomorrow morning
