I don't really see this as a delta issue. If the stock isn't doing what you expected, or it no longer looks like it will do what you expected, you should close or adjust the position.
If you thought your AAPL option was going to expire OTM and you still think it will recover to OTM, hold on to it. If something fundamental about the company has changed, and you are no longer bullish on it, roll down or get out. If the drop was severe enough that you think November isn't enough time for it to recover (i.e. it threw off your timing but not your overall outlook), maybe rolling out a month is the right answer.
TLDR version: It's about the stock, not the option.
