AUTOFLOWER / Which Leaves should I cut?

none. that plant has no leaves that should be removed for any rational reason. any overlap causing constant condensation on the leaves? that's a good reason. but this plant is airy and good airflow, so there's not much congestion to be concerned about. also, if you can simply bend the leaves so they don't touch, that's WAY better than removing one. CO2 is your limiting factor. not only does removing leaves reduce photosynthesis potential, but it reduces co2 intake (transpiration). leaves are the lungs. check out 'to defoliate or not' on cocoforcannabis dot com. in fact read all of dr photons articles and their guides. it'll clear up a lot of stuff and make you more impervious to "bruh-science" and other anecdotal nonsense out there.
