oneeyeluke said:The tender new leaves will always start out a lighter color. If you waited two weeks before watering and see leaves that have wilted then you need more water. To be honest, I think your plant is doing very well and no need to do anything different. You are watching your watering well and you already know, umbrella plants do best in bright, indirect light. Keep us posted if any new changes occur.
WillC said:Your Schefflera is recently out of the ideal conditions of the greenhouse. Those conditions cannot be duplicated in a home environment, so you should expect your plant to adapt by slowly losing some of its older leaves. Over time, the plant will thin out some. That does not mean it is dying; just adapting.
As long as new leaves come in and remain healthy, then everything is okay.
Don't let any more than the top one inch of soil get dry before you water.
