Robertsanswered grow question a year ago I would wait till she stretched to do anything. It is not a ideal practice to top or mass defoliate a autoflower. They lose grow time as they recover, which takes away from their size. Plus it is very stressful. I would not be surprised if your plant hermi's from all of that. Lst and selective defoliation with a canopy lollipop after stretching is all the more I do personally to them.
