not to worry about, but i would remove all that you see..because it is putting energy there to form buds..but the buds forming there will never be good dense quality..so i would remove so the plant can focus that extra energy on the upper range of the buds.
Just remove all the buds/hars/little leaves leftovers etc that now don't even have light..waste of energy.
Unless you want to reveg the plant after harvest..then i suggest to leave them there, because new shoots will come from those places if you reveg
