first grow with clones - need advice.

I added three clones to my current grow from seed and I was wondering if there is any "special" advice in dealing with how scraggly they are. Basically my (4) seed plants are bushy as hell and look good. The clones are about as tall 8" but long spaces in between nodes and not that great looking (they look healthy, just not bushy). Should I top them or LST or just leave them? I have never grown from clones before.

I looked at probably 5-6 different dispensaries and all of the clones looked like the ones I bought. Sorry I don't have a pic. I will try to get one tonight.
