The first common mutation we’ll be looking at is a tri-leaf sprout. Usually, when you’re sprouting cannabis, you’ll begin with two starter leafs which are circular in nature, and then two small cannabis leafs forming. However, in some cases, you can see a third cannabis leaf in the initial sprout, meaning you’ve got a tri-leaf mutation. While in general terms, you’ll treat this plant no different than a bi-leaf sprout, these do have about 1/3 more side branches than your typical plant – meaning that this mutation can be functional when training.
