It’s really up to you. I’ve topped my autos with good results. But more recently I’ve been giving them a FIM pinch at the new growth tip - just a firm pinch on the tip. This causes less stress and still helps to produce more bud sites. Also, don’t take the 65 day timeline provided by the breeder as absolute, my autos always go at least a couple of weeks longer than advertised. Good luck! 👍
