My guess is that you just stressed them out for 5 days and they probably froze. Will likely stretch a little more and then keep popping out hairs. I doubt you got them to go all the way back into veg mode. You are probably just a week behind. There are some people who top or defoliate on purpose during stretch. It slows the stretch way down because the plant has to recover and then once the plant recovers it stretches just a little more instead of a lot more. I personally don't like that idea but to each their own. I also don't have those kind of height limitations that they did.
Honestly I think you won't see any balls. You'll likely either see them start to stretch a little again or they will start pumping out hairs and the stretch is over and they will just move on. I don't switch around my lights as I use all LEDs but I don't think I'd mess with anything else at this point. Another error with the timer or something might just push the plants to the edge. Take a deep breath, then take a deep puff and sit back and watch. In my opinion there isn't much you can do to change what is going to happen in the next week or so.
