Think ahout photosynthesis man. Remember that's the process where plants use light to convert nutes into sugars. That's how they feed. As the bud ripens, they will turn yellow & drop after they've released their stored sugars to the buds. Once my plants bush out, I take fluorescent fixtures with grow tubes, lay them on the floor facing upwards to light the shaded parts of the plants. Just place them where they are needed the most. If you can't find grow tubes, use cool whites for veg, warm whites for flowering. ~~~PEACE!~~~
