Just straight water for a few weeks until they get some roots going, then gently increase nutes if you are just using plain soil. (1/4 strength a week, then 1/2 strength, then 3/4, etc.) If your using soil with nutrients already in it, you won't need to add nutes for a few months, or ever if your transplanting properly. Use gentle light on the clones also....they won't be ready to do a lot of photosynthesis until they get some roots down either. Hope this helps!
