Stretching! pics! please help!

As you can see the sensi star on the right keep which is about 5 weeks old (2 weeks veg. 3 weeks flower) is 2 and half feet tall. The ak-47 on the left is 2 months old (1 month veg. 1 month flower) is only 2 feet tall and very bushy.

I have no idea what tthe deal is and if the sensi star which is a long flowerer grows at the rate till the end I'm going to have to grow it sideways

By the way the haze is under an 1000 watt and the sensi under a 400 watt. This is only temperary the sensi and ak are about to go under the 1000 watt and a 12 sea of green plants under the 400w.

move the lights closer

The increased light should reduce further stretching.

Lights are too far away. Keep em as close as possible to the plants without burnnin em.

The picture is from a wierd angle. The 1000 watt light on the left is only 1 foot from the plants. Any closer and is burns I've tried. The 400 watt on the right is only an inch away from the sensi star plants but isn't burning for some reason.
