That doesnt really look like bubba to me, the branches look too thin and spindly to be bubba, looks like maybe some bubba/og hybrid.
When I top my bubba it doesn't shoot out laterally, the next node under where I topped will generally correct it's posture and start growing in single cola dominance again. My bubba has very thick branches that grow stiff and close to the main meristem.
The way your buds grow along the stem remind me of OG, the way they are spread out and grow almost in a zig zag pattern, bubba buds grow fuller and longer along the stem.
I'll post more pictures in time. The plants look different depending what room they are in and what environmental conditions they are exposed to. The other room has bigger buds and I think the plants looks much different than the plant that I showed. I'll try and snap some pics soon.
