There might be a couple leaves you could remove, but it's a very open plant as is. As far as pruning anything off.. down low, small growths near end of vege growth (stems and leaves before fully focusing on flowers) It's an auto, so that becomes more of a guess, if you try to do it a couple weeks early to focus more resources into quality later.
I'd be conservative, if it's your first time doing it. Leave more than you think... see how the plant grows at various depths relative to your light and environment you provide. The larf will typically be at the same level. each time.. .you'll better recognize what's wasteful to leave on the plant and turns into a 4" stem with trash on it (lol)... still learning, myself.
a little extra larf doesn't hinder the development up top.. a lot of larf does. Larf provides way better yield for edibles or hashish sieving too, than trim.. i don't even keep my trim, if i have some larf for bubble hash.
