guys, when is ideal time to top the autos? 2 weeks ? after 4 nodes? im in 2 weeks now and my fourth pair of leaves is coming out. should I top now or wait another week to get them stronger?
Never. You
can top auto's with no ill effect (Ive done it many times) but, you're not going to get more total weight, you get more, smaller buds. They're still on that limited timeline.
My experience has been better with LST or simply super cropping to keep canopy in check.
That said, best time to top an auto is a couple days before pre-flower stretch (instead of stretching, they throw branches like crazy). It's better if you've grown the strain before so you time it right. You end up with a smallish bush with a ton of quarter size buds. Pain in the balls to trim too.
Oh, on topic, I'm growing some Twisted Tree Lemon OG auto's to double check if they're as mediocre as I think they are. Unfortunate, as their Twisted Cookies is right up there with some of the best auto's I've grown. Must be why the Cookies always sells out fast.
