When should training and topping stop on the autos ? Wait untill I see budding ? Or much earlier so it has time to add growth and size

I agree I would not top an auto. just LST.

I woudln't top an autoflower. just train it. DLI is the primarfy factor for yield. Training just distributes it more evently when done well. The goal of that is less proportional larf of total yield, imo.

Topping I would do after 3 weeks and stop training HST at 1212. LST during stretch should be OK but not longer. Much success and Happy Growing
