I’ve been seeing so many things online and am really confused about when I should be feeding my starter. I fed it at 1230 pm and it’s 1030 pm now and looks like this. Can i leave it until the morning? Should i feed before bed? It does take 6-8 hrs to double. Can i start baking with it?

After failing my first starter attempt, a friend gave me 20g of her starter which she uses for baking. I fed it this morning at 730 am with a 1:3:3 ratio and it still hasn’t doubled 13 hours later
