Are these cuttings that have just been rooted? I do see new growth on one of the plants, so that's good.
In my experience growing scheflera over several decades, it is extremely hard to over-water IF the soil is well-draining. They actually love constantly moist (not wet) potting soil. To my eyes, the potting media does not look like Miracle Gro potting soil, at least in the scheflera pot. I don't see any perlite and it looks like there is some sort of bark there. Perhaps Miracle Gro has changed its formulation. Actually, if that is bark, I like it in my potting soils. I do put quite a bit of coarse perlite in all my houseplant mixes, but I customize all my potting mixtures depending on what I am growing.
