I got distracted last night by another project and didn't collect my full volume for the boil on my hefe. The airlock is barely bubbling now, and I just boiled 1 gal of water. The water is on ice now to get down to 70, and I was going to top off the fermenter, but it just occured to me this might be bad. If fermentation is just starting (14 hrs after pitching), am I ok pouring the water in?
