Starter gets sluggish
I got an established starter from a friend back in January. Ever since I would feed it consistently (once every 24h) and I would do 1:5:6,or 1:4:5. I also have another jar of it stored in the fridge.
The starter was very live and bubbly at first and then after 2 -3 weeks of consistent feedings it would slow down ( wouldn’t double over 12h) and get all sluggish. So I would have to get the starter that’s in the fridge and start over by waking it up and feeding it consistently and then it would again eventually just get sluggish. I am keeping the stater in my microwave with the door slightly open ( so it’s warm from the light). My kitchen is at about 20-21 C and I’m feeding my starter all-purpose flour. Anyone had this happen to their starter?? Would appreciate any tips
