No, don't defoliate. It is the leaves that make the energy that makes the flowers grow.
Flowers do not grow on there own, they are the resiult of the energy that is made from the leaves.
Less leaves = less buds.
Try only to tuck the leaves of autos and not defoliate them especially in flower.
They can go into shock and do weird things like stunned growth or just bad yields.
Good Luck.
