I agree with harbinger. You’ve got a real stretchy sativa here and she’s lanky and airy. Trimming lower bud sites at this juncture won’t do a whole lot given that you’re through most of transition at this point. You still can without detrimental effect absolutely, but it’s really not going to make much of a difference on the scales. If it were me, I probably wouldn’t bother. I’m greedy as fuck when it comes to my yields and there’s more than enough light penetration in the canopy to turn that little budlet into a decent nug. Best of luck with it!
