It looks lively enough, but if it's making that much hooch, you're underfeeding it.
At 24 hrs I discarded some and split up and fed
You need more flour, less seed culture -- how much is 'some'?
If you don't have a scale, you *need* to get one. It will make things so
much easier when you start trying dough formulas.
Try taking 20g of culture and feeding 100g flour & 100g water.
Or, feed a tablespoon of culture with 1/4 cup of water, and enough flour to make a *thick* batter.
Put it in a clean jar after mixing, so you can see the "high water mark" if it rises and falls while you're not around.
Use a rubber band or a piece of tape to mark the 'just fed' level, so you can see how much rise you got.
