In answer to your question about nutes: You should try my nutes!
Anyhow, I wouldn't be too concerned about the leaves that are burnt-- if they were the original leaves of the clone. They typically yellow up like that when new legs are sprouting, because it is using up the nutrient reserves in the leaves to make the new roots.
The new growth coming out of the clones seems decent. No signs of trouble - yet.
You should water only when the soil gets dry. If your container is too big, then it'll take a lot longer for the soil to dry out in between waterings. Ideally you want the soil pots to be as light as a feather when it's time to water.
