That's cute that you'd think that this would affect your plant... cannabis is pretty tough. Plants in general are.
I clipped a few buds (including a top) from some of my plants (various reasons, taste testing being one)... bonus: more light penetration

. I have before... I usually can't even see where it was after a while. Depending on stage either the bottoms veg out and fill the space and make buds or the buds on those lower ones fill in/fatten up... I highly doubt it makes up for the loss in the final weight, but it certainly doesn't affect the health of my plants, or how well the rest of the plant produces. Doesn't even slow them down. Plants have a harder time with stress than trauma, mostly.
Heck, I was LSTing a plant after I had topped the main stem (not right after, like a week after) and I spread the opposing stems so far that the main stem split down the middle an inch or two. I didn't have a good way to fix it, so I used some twist tie to hold it back together. It healed fine (not totally rejoined, but all healed over) and I don't think I noticed any difference between that plant's development and the rest, and certainly none today.
If you were topping (which is basically what you did here) all the tops (back when it was vegging) then it would slow down, as the new shoots take off...
Moster cropping... cool... mental note.
At 30 days into flower my buds are already mature enough to smoke (but they look more mature than yours... with fuller calyxes and a number of curled/ambered pistils... <50%?). Even given their age, a quick dry and no cure there's no harshness at all in the taste (though maybe I am coughing more per inhale) and while not as potent as I expect the final product, very good... not as long lasting is the main thing.
