2nd node in a week is good... Just from now on, make sure you have plenty of drainage holes and even some air holes on the bottom and the sides of the pot. You want the soil to be nice a airy. It will compact over time, which is why the perlite is so important... more so with manure. I'd say go for at least 30% perlite.
