I'm on my 4th day of feeding my sourdough but there is always what I think is hooch on it. Right now it's really warm in my home, around 30C (86F), I've been keeping this tucked away in a cupboard so it says cooler than just leaving it out. Currently I've been leaving around 70g of starter and putting around 70g of whole wheat flour and 50g of ap flour with 120g of room temperature water. I'll feed it roughly every 24 hours. There's some activity (small bubbles in the starter) it also sometimes bubbles when I open the lid to feed it (I haven't kept the lid on very tight). There's also a sour-ish smell. I'm just worried that it isn't getting enough food because of the hooch. I'm worried that if I feed it twice a day with the same feeding I would overfeed my starter. What should I do?
