Late to the party but they can be topped, just do it in veg.
I prefer to fim once and 4 tops rather then topping to produce 2, topping is more stress than fimming as well.

I have spoke to this topic many times on countless posts, so I think it’s time to concentrate that information into one linkable post.
FIM’ing is a medium high stress pruning method to increase yeilds and allow of a more even canopy. While topping a plant will result in two main colas a fully successful FIM will result in four colas! This works equally as well on autoflowers as it does on photoperiods.
I personally suggest FIM’ing at the 4th/5th node.
After your FIM is complete no other train…
