This plant is way to tall

Never cut your plant at all after flipped to flower, except for large fan leaves that cover buds, if anything. When in flower, the plant doesn't work on branching or creating much foliage and is focused on making inflorescences (buds). What you can do to reduce height is to use LST, low stress training. Use gentle twine or nursery string to bend the branches down. You can also use supercropping, which is when you squeeze the stem, and bend the stem down at 90 degree angle without breaking the bark of the stem.

dont top her, use some gardent stakes and some wire, gentle bend her away from the light. right now you can up a net or something, and basically control the height really well
