clone wars

I have been trying for about 4 weeks to successfully clone my outdoor Veg state plants (holland's hope) into my hydro GH Eco Rain system. The problem that I am having is that the the veg part seems like its dying but the roots are growing. Isnt that weird? Will the leaves come back? My light (hps) is about 18 inches away. My nutes are right on according to the instructions. And one of the 6 is growing quite nicely. Last grow I had no problem cloning.
Any comments are appreciated.

I used to have that problem occasionally. I took the light out of the equation...clones don't need a ton of light, just enough so they think its daylight for most of the day. Mine now sit in the living room under a humidity dome.

Just keep misting them to make sure humidity stays up.

My success rate on clones is nearly 100 % now.

hope that helps
