those look like re-veg leaves. but without looking at the whole plant anything leaf related is difficult to diagnose.

You get scabby looking leaves from time to time without reason, usually near the bottom of the plant. it's when the whole plant takes on issues that you need to concern yourself. so without seeing what's going on with all the leaves  it's hard to tell. 

but my experience tells me these leaves are the ones that start up when it wants to re-veg or has already started. GL
