Is my starter failing?
I am trying to create a starter using the method given by sourdolady. I am on day 4 of feeding the starter with unbleached all purpose flour and water. When I switched to flour and water on Saturday, I was still getting good bubbles and doubling in size after feeding. Maybe not as many bubbles as I had with rye flour and orange juice though. Slowly over the past few days my bubbles have been reducing and it has stopped doubling after feeding (isn't even rising anymore). Today it has some bubbles on the top, no bubbles suspended within the starter, and is producing a lot of clear liquid. The starter itself also seems much more liquidy yesterday and today. It doesn't have the consistency of pancake batter anymore. I have been feeding it twice a day, to try to keep it active. I did start giving it 1/4 teaspoon of cider vinegar with the feedings yesterday. Do you give it vinegar each time you feed it, or just once a day? The temperature in our house has been fluctuating a lot the past couple of days and has not been as warm, would that have an effect? I put it in the oven with the light on this morning hoping to give it a more stable environment. Is this normal activity? If not is there anything I can do to save the starter?
