I've heard topping autos is ill-advised. Any ...

Top it!!!! That’s what I’m doing next , check out my defoliation grow experiment. People advise not to do that also but dawn I’m seeing results! My next grow is top or lst not sure Good luck and do what the munchie guts tell you!

To top or not to depends in the strain....( we are talking about automatics) there are strains i wont top at all like some of the red/ blue family. Or some very classy stains. But all the others if they grow vigor you can top without problems. some strains you can treat like photoperiods ( mainly the "newer genetics" with alot of skunk in their ancestors. You see it latst in day 21 if you have agood grower or not. Iam topping most stains at least 1 time if they grow very vigor i do it more often

Many growers recommend against topping an auto plant because stress can stunt your plant. While you definitely want to avoid stunting, I personally think topping autos works well as long as you make sure your plant is healthy and fast-growing first. To be honest, other factors like overwatering or a poor environment seem to be much more likely to stunt an auto-flowering plant than topping, especially if you’re cutting off just the very tip of the plant without removing much plant matter.
