Jam, your plants are really stretched, and this is good you can make a lots of clones now! This light in your box can't handle more than the third of the plans you have now. You are supposed to have tiny christmas trees, but you will have big streched weed with small bud to plant ratio and your yield will fall.
First: put your lamp across the box (not along)
Second: add another hps to hit 800 watts of overal hps lighting
Third: cut down your bushes for clones and start your grow over.
And you will get yor sea of green christmas trees!
