Nodes

Hey, buddy. Nodes with parallel foliage are characteristic of growth while alternate nodes are characteristic of flowering. Some strains may not be very well stabilized and the time of flowering may depend more on one mother strain than another. Basically if one parent tends to start flowering faster than the other parent, if the strain you are growing is not very stable, you may have differences in size, volume, shape, and also differences in the growing and flowering times needed for each, which could explain the noticeable differences you have on your plants.
