You definately need a lot more light. How much time elapsed from the second picture to the third (where the plant looks super tall)? Is that the light on the side of the plant?

Remember that watts can confuse people in regards to lights. An HID of the same wattage as an equal amount of floro's will put out a LOT more light because it uses the amps more efficiently.

If those buds get much bigger you may have to tie all of them up to hold the weight on the stretched stems.

Good luck bro
