Hello there, I'm new to all this cloning as well, however, I've done some reading on the subject, and I don't know if you should be mixing Rhizotonic with Formulex. Rhizotonic is root nutrient, and Formulex is plant nutrient. The clones are too young for Formulex, and even when used for misting with Formulex, it says use weekly. I've got my clones in a propagator, with the rockwool cubes soaked in Rhizotonic, and I mist them regularly with Rhizotonic. I'm sure I'm right in saying that it doesn't matter if the leaves die slowly on clones, because the plant is using their energy to stay alive, and focusing all its energy into root growth. Stay with them, it will probably take a few weeks! Good luck, and keep the faith.
