It depends on the strain. If it is growing vertical with very little side branching I don't do it but if there is good side branching I will. Depends on the lights I am using too. My T5 I like to top and put my plants tops a few inches from the light and it works out good. My 600W HPS I might not top because I don't have to worry about light intensity. If I was planning on topping I would leave the lights on for 24 hours a day. As soon as I see a pre flower I will top usually around week 3 and around week 3 or 4 I will turn light to 20 hours. I did this light schedule for my last auto but did not top and it made for a good bush.
my blueberry bliss handled topping very well while my amnesia haze is struggling to stay healthy. I think Joe is correct about it depending on genetics

Hey mrmojo how far along are u on the blueberry bliss grow? I got one going now. Although I didn't top mine I did a modified defoliation. And couldn't believe the result. I took more from one plant as far as removal. And am in total agreement with you guys about genes and would go so far as to say plant to plant.
