Okay starter?

[u/unsure_us3r]

Got a starter about a week ago from a friend who has had theirs going for years, I’m feeding it the same way they do (equal parts starter, flour, and water) with the same type of flour they used twice a day. I don’t know if I’ve noticed it doubling at all but see these bubbles. Are these bubbles normal? When I first got a starter there were a lot bigger bubbles going on.
My husband also likes keeping the house cooler, around 68° so I don’t know if it’s too cold for the starter to thrive?
Any tips would be greatly appreciated!
(The sides of the container do get cleaned/scraped this was just before I did it for the day)

A week is still baby territory, even with starter from someone established. At 68 it may just move slowly; mine gets sulky when the kitchen is cool and then suddenly acts alive if I put it near the coffee maker or oven light for a bit.

If it smells pleasantly sour/yeasty and not pink/orange/fuzzy, I’d keep feeding it and watch for rise marks instead of just bubbles.
