Starter is sluggish after refresh
I have a fairly new starter, about a month old, that I've been keeping in the fridge for a week. I took it out of the fridge on Wednesday to refresh with the hopes of baking with it this weekend. When I took it out of the fridge, there was a layer of hooch that I just stired down. After feeding, it is not doubling as quickly as it was before I stuck it in the fridge. I'm keeping it at 100% hydration and am feeding it 1:1:1. It has been almost 10 hours and it's only risen about 50%. The house is on the cooler side, ~68 Degrees F. Is this normal behavior? I hope I haven't killed it.
