There tends to be more respiration on the underside of leaves. This is purely due to the fact that stomata are prevalent on underside of leaves
(see here). The function of this organ is to breathe, like our mouths. This is where H2O leaves the plants as a gas. If a leaf is directly underneath another leaf it will cool the gaseous H2O
(like a condenser works) and result in a liquid state H2O left between leaves. That is
just why it is happening though. I would just make sure
adequate canopy air circulation is met.
Leaves being close together is a sign of close internodal distance and means your going to get denser buds
(see here). Your plants seem to be functioning in a healthy manner. However, in my opinion, the environment is not waiving the leaves and moving humidity/air adequately.
Keep your room below 60% humidity from here on out, and increase the direct plant-to-air contact via a circulation fan.
In my opinion I would really only cut leaves if they are casting shade on canopy-penetrating branches, or when loli-popping/super-cropping. I would suspect your plant is just heavy breather and needs more airflow.
Best regards!!
