Hello friends, i was wondering if i can cut off lower branches and buds that aren't getting the light as the tops are? I cut lower branches a couple times already since they were a foot tall in veg. Its a sativa dominant Quantum Kush, it has plenty of air flow but lower stuff that isn't getting light should i cut if off or is 3 weeks to far?. And i have fan leaves well under the canopy that are still in contact with plants that don't get any light, should i just remove those as well? Thanks
