I have 3 different varieties of MJ plants in my outdoor garden. The plants are 4 or 5 feet tall and appear healthy, however, the lower branches keep collapsing to the ground. We’re juicing the leaves for medical marijuana, so it’s not a terrible loss, but it’s never happened before. The branches just break at the main stem and there is just a sliver of the branch connected to the main stem. I cut the branches and it seems to heal over quickly–but the plants are naked below 2’ now. Any suggestions?
