uneven lengths... some help pls

Hey guys,
So I've got 5 beautiful bushes... but the problem is 4 outta 5 are a foot tall, while the 5th bush(which i transplanted early into a 5 gal) is a massive a little under 2 feet... my 400w mh is very close to this monster.. not burning it yet and the temp is still resonable tear my giant. Imma want to flower soon... but even if i do the monster bush will outgrow the light possitions for the other 4 plants, pushing the light up, and therefor there will be less light for the other 4. i was t hinking of toping the monster... but then again... i donno if it will realy help. What do you guys think i should do?
Cheers,
Sof

stack some wood blocks, or whatever, under the short plants to raise them up equal with the tallest one ... :p

or, bend it over, tie it down, ... it will develop more buds along its length ... :smokin:

good idear...
