It's hard to tell without a pic but you MUST know the pH. You mentioned that they are clones, how old are they? Do they have established roots yet?

It could be nute lockout, the soil could be too hot (nutes), or it could be anything.

If you dont have a pH tester, get some pH strips. They are very cheap and work well enough.
