Its called FIMPinch the leading tip of each shoot in that mishmash while it's in veg and double your bud harvest.
Just cut off the growing tip. You can do it to any growing tip on the plant. Soon you'll have more side shoot growth and than more tops. I'd give her a week to recover and upper growth to resume.
