Defoliating and lollipopping

So I’ve read a lot of conflicting information and options on here. When have you found is the best time to start defoliating and also the time to lollipop? Some say it’s best to not start until flower stage and some say otherwise. This is my third grow and I’m just wanting to keep perfecting my process. Hopefully each grow getting better. Thanks for the info in advance.
