Sloppy, if there still stretching , try moving your light 2-3 inchs from the top of your plants. Most plants will grow and stretch towards the light to get the most light, if you put the light 2-3 inchs away from the top of the plant you can stop the stretching and still have growing space within that 2-3 inchs, as the growth increase's you move it up according to the growth.

Gl to ya mate, cheers.
