Help with sourdough starter
I am new to sourdough. Decided to give it a go last Monday using the method on the KAF website. I started it with KAF White Whole Wheat flour and fed it KAF AP. Per their instructions, I have been feeding it twice a day every 12 hours. It has bubbled nicely but it has never risen.
I saw some posts from this site that said it won't rise if it's too thin, so on day 6 I did my morning feeding with the 2:2:1 starter/flour/water ratio but there was no movement and no bubbles so I went back to 100% hydration.
Today is day 8 and still no rising and it doesn't seem to have much bubbling either. It is 75°F in my house during the day and we lower the AC to 72° at night. I have it covered with plastic wrap. It does have a nice aroma to it, sort of fruity and a touch sour. I also have a kitchen scale so I weigh all my ingredients.
Did I somehow kill it? I've read here that it does have a quiet period and after a few days it should start doubling but it's been quiet since day 3. On day 6 I also started adding WWW flour with the AP for feedings.
I forgot to mention I use bottled water.
