Whorled phyllotaxy means thre branches at every node, dose not mean extra yeild though just the same as a normal plant except the buds are split over a large area. Not genetic but just a plant exspression, yours is a triploid meaning three leaves and quite often this will grow out, triploids do not generally stay triploids for long, i have a few whorled phyllotaxy plants at the moment and believe me i was gutted they didnt produce a third more. Triploids are genetic variants i believe but the genetics stabalise back to a diploid or two leaves per node.
I believe some master kushes are triploids but cant remember totally. Good luck dude it will be allright, just somthing that happens now and again. Peace
