I think it is a sign of good growing and healthy plants. The root beer rock candy i grew from seed, did not do this. When I grew out the clone run two of the three did do it. I say it is because i was better in tune with the plants needs after having grown them previously.
Leaf buds, the final chapter. I forgot to get a pic of the 3 together on the buds. Here are just a few of the leaf buds on the 1 Jack 99 plant.
I was hoping on a joint. I won't get that but there is plenty for a leaf bud bowl though
