Those look amazing. I saw something similar. A few of mine looked smaller but they pretty much all caught up with the SB.
Test both, see which one makes you feel frisky.
LOL
Think of it as an adventure. Keep smoking until you can tell the difference.
Honestly, there probably isn't much difference in the first place but if there actually ends up being some difference it might be a nice plus.
One thing we can say. Sex bud grows just as well as their regular c99 so we haven't lost anything.
Sex bud is supposed to finish a week earlier, so maybe the first one to finish is your SB. If that's the superior one on the right, that might be a good guess.
My SB is still the superior plant of them all. Maybe this is what they mean by "enhanced."
