I have fimmed photos but not autos. In my current grow I have one plant that was transplanted to a new pot at about 7 days. It def is behind all the others planted at the same time by at least two weeks. I am thinking now that it may not produce that much at all. So what I am saying is this : The line of thought I have seen the most is that doing any topping, transplanting, etc is hard on the autos. This transplant kinda confirms that for me. However the fimming isn't removing anything, so perhaps then the plant isn't affected as much as topping would cause. Interesting. Another experiment for next time indeed!
