Little white crawler..what is it?

Just found a small crawling white bug on top of the leaf as I was moving the leaves around thinking of lst'ing. Killed it and cant find any others, but this was on the plant that is showing some issues for a day now and growth has slowed. gave first feeding on sunday..im guessing the issues are because of the feeding, but wondering what the little white bug is.

Should post a pic bro.

It was tiny and suddenly appeared..i put my finger on it to kill it on the leaf. Im searching on google now, but cant find anything similar. It wasn't a white fly, I checked for any marking under the leaves, I don't think I see anything. We'll see.
