Starter Slump

Toast

My starters were going strong in my warm cabinet until the weather cooled. I ran out of my malted bread flour/yecora rojo I used to feed and used AP/yecora for a week to no avail. I bought a big proofer and put everyone in there at 78F and then they were rising and falling too fast. Now I have my regular feeding flours and after reading up on this a bit I think I need to use a 1:1:1 feeding to restore my babies. Am I on the right track?
