Certainly can lollipop them, but go easy on the defoliation.
ALL of the plants energy to grow and thrive is made by/in the leaves.
Just remember.............
Less leaves = less energy being made = less potential (flower) growth.
You would be better off "tucking" large leaves out of the way rather than cutting them off.
Increasing air flow while avoiding defoliation is easily achieved..........think outside the box...........
Herms are generally a genetic thing, not a leaf quantity issue and lots of leaves is not a stress issue that could lead to hermaphroditism.
