Hey guy, i've been having clone troubles lately too, all of my peat pellets molded up! lol, but to me it sounds like the problem youre having is the lights are too close to those babies. fresh clones are very vulnerable, you have to baby them for a while. not all, but most people put a humidity dome over the top of the clones. if you don't know what that is, there are a lot of threads on cloning you could look into. they keep a bit of humidity around the leaves of the clones, which keeps the leaves green and lively, but, as i have now experiences twice, too much trapped humidity causes mold and the loss of all those potential buds. the superthrive though, i doubt it did any harm to the clones. although i don't know if its good practice, i supplement all of my waterings with superthrive, even when i don't put any other nutes in. just be careful and follow the directions on the bottle, because that stuff is pretty potent. hope i helped some, have a good one.
