SuperThrive is brutal and can easily kill newly rooted clones, so its likely thats what did yours in if they didn't have roots. I don't water my clones at all, I just keep the dome moist. If you water whatever they are planted in (I use rockwool), the ends usually rot where the roots are supposed to grow. Plus, watering below soil won't do any good since there's nothing down there to water. You have to let the leaves work the magic until there are roots.

New clones, leaves turning brown and curl I recently planted two clones. i put root stimulator on it. planted it in soil. and put it under a 23watt CFL and a 15watt CFL (all i have at the moment.) about 4 inches away from the plants, and about 1 inch away from the dome. I watered them with SUPERthrive. was that a no? anyways... the leaves on the bottom of each clone are turning yellow and curling up and eventually turning dark brown almost a black. looks like the leaves died on the bottom. should i cut them. they are kinda Rating: 5
