What yellow stuff?

Did you look at the picture? Theres yellow clumps. I was just wondering if this is anything to be concerned about. They weren't there before. I wonder if its a by product of cheap potting soil.

Tough to make out but perhaps effloresce from fertilizer?

That yellow stuff is minerals in your patting soil reacting to fertilizer or your water--it poses no threat

Looks tan-brown to me. It will break down if sprayed with water. It's nothing to worry about.

What kind of potting mix did you use and what are the ingredients?

It looks like it is one of those mixes with compost in it?
