whorled phylotaxy AKA trilateral branching.. isnt when one leaf is growing faster than the other its when you get three nodal points on a plant so to say. if you look at a lot of plants they will only sprout from two sides opposite each other, when trilateral branching occurs you will have more than just these two
.
i believe it to just be some form of mutation such as warping more than likely.
IBL strains often show them and in a lot of cases the condition can breed true.
also you dont move your plants around do you it may just be the way they keep trying to move towards the light.. i think one f westies babies may be going through this its could be why his leaves are warping out.. either that or maybe mild light or heat stress.
