What is your leg routine. List exercises, sets and reps.
And I agree with the rest of the guys. This is where a lot of the "smaller" or "skinnier" guys go wrong thinking that carbs=bodyfat. This is not true, its your carb choices and all together your food choices. You may not lean out tremendously or anything but you gotta pick a route, I'd say continue to bulk up, but go about it in a smart, calculated manner and you won't gain all this dreaded bodyfat you worry about w/ lowering your carbs so much
Remember like alp said protein is the only macro that can build muscle so now you need energy and thats from carbs and fat. If you don't have enough of the other two while trying to gain muscle I bet you can guess what your body will use for energy.... what it should be using to build......
Add carbs in there bro and time it out right. What I do is 4 meals before I workout with carbs and 3 meals PWO w/ carbs and my final meal(s) are protein/fat. I don't venture over 12% offseason or lose my abs... I'm thinking you should do the same. But i know you don't eat as much as I or need to for that matter (not yet at least

) so 3 meals before, 3 meals after IMO
I stick to oats, brown rice, sweet potatoes, ezekiel bread......
