HansGoatanswered grow question 9 months ago Only defoliate where leaves give problems. For example when a leaf is blocking the light for a huge part of the plant (or another plant). And when the leaves are stacked on each other blocking airflow. But when a leaf doesn't give a problem like mentioned above there is no reason to do another defoliation. And never defoliate after when you notice the first pistils (white hairs). Enjoy your grow buddy, plants are looking great!
