Gently tie the cola down, as suggested. You don't want the plant touching the light.
The reason you have so much foliage is because of the light. As was said, you're using weak lights, the plant is making up for it by growing many big leaves to capture as much light as it can. Leaves are the solar panels of the plant, removing them doesn't help.(See Uncle Bens "https://www.rollitup.org/marijuana-plant-problems/158144-never-ending-abuse-phosphorous-bloom.html-a good read). Be sure to keep them healthy along with the root structure, and the buds will follow.(It isn't the buds that need the light, its the leaves). If I were you i'd get some 300 wtt cfls. they are between $20-$30 and you WILL have better results. There is a forum on growing with cfls, and you can get so great tips there.
Also,I don't think you've fed them enough. It sounds like it needs nitrogen.
Hope that helps, GL
