Lime worked for me. You can see in my grow. I used lime the same way you did and quit using nutes for a week. Just molasses water. Now my leaves are shiny like they have oil in them . Id say no more nutes because your soil has alot locked inside it. Just molasses! They will bounce back . Yes your looking at 20 or more days on those girls.
