hi all! new member here :)
a few days ago i picked up a new variegated schefflera houseplant for my apartment. i noticed today while repotting it that there are some black web-like things on the bottom of some of the leaves. it only affected 2-3 of the bottom leaves of the plant.
i'm posting to ask if anyone knows what this might be? should i be worried? should i remove or treat the affected leaves, or just let them be?
i've added a photo of the plant and one of the affected leaves.
i hope one of you might know! i'm new to gardening so it would be great to get some insight from knowledgeable gardeners!
thanks!

I'm not sure what it is but as its only affecting 2 or 3 leaves, I wouldn't worry. My bigger concern is the mounded up soil in the pot. Did you put soil on top of the old root ball or cover the stems? If so, un-do as both will cause stem rot and death. Your soil also looks very dry, remember to water.
