One stunted-looking leaf
 

One of my plants (Sugar Lump) seems otherwise healthy, but has produced a leaf that is stunted, narrower and smaller than the leaves around it. It seems to have tiny white specks on it.


Leaves above and below it are healthy. I'm not sure about what is causing this or whether I can arrrest this by pinching the leaf off.

Any advice welcome. Thanks.

Sounds like a sucking insect perhaps. Pick or off. A tomato can spare plenty of leaves. Is it an entire leaf or just one leaflet.

Hi KarenO, it's just one entire leaf.

I ended up pinching off and discarding the leaf in the garbage. The underside had very tiny little white insects on it.
