To top or not to top?

I generally recommend topping only after the fifth node, because I feel the plant isn’t strong enough before that point. I also top autoflowers, since in my experience it helps prevent mold. When I don’t top, I usually end up with one large main cola — and that’s exactly the part most prone to mold. Topping doesn’t just split the main cola; it also encourages the side branches to grow more vigorously, leading to several big colas and a more balanced canopy. Feel free to check out my grow diaries to see how I do it. Keep in mind: topping is always a form of stress for the plant, and every strain reacts differently. That’s why it’s important to ease into it and observe how your plant responds. After topping, they typically need around 3 to 4 days to recover. Only then should you consider flipping to flower. I personally keep my plants in veg for about 4 to 5 weeks before initiating the flowering stage. But you can also top now — after the fifth node — then wait another 3 to 4 days before switching to 12/12. Or wait even a bit longer if you like. The great thing about growing is: the one true rule of growing is that there are no hard rules. As for defoliation: I usually start around week three and then do a bit here and there as needed. You can remove a few large fan leaves to open things up, but don’t go overboard — the plant still needs enough foliage to thrive.
