Im sorry to.say this, but one thing people forget is that just because there is enough light to see doesnt mean that its sufficient light for growing. With that light, the intensity is only sufficient for good growth within like 2 feet of the bulb, all your lower buds will probably be straight fluff. Its better to keep the plant as short as possible so as to ensure as much of the plant as possible is in the grow.zone of light intensity. In the future, try double topping your plants, and keep that light directly on top of it. Flower when the plant is 1 foot tall, trim off the lower branches. Try to direct all your bud growth into one compact well lit grow.zone to maximize the relationship between yield and quality.
I hope you dont see this as me putting you down, only trying to tailor some info for your situation
