Anyone know what this was on my tomato leaves?
Lots of small dark spots, mostly on the lower leaves. Greenhouse grown. These photos are from last season, but I never figured out what it was. Fungal disease or nutrient issue? Any help appreciated.

    Looks like it, I think if they were bigger and start to turn purple it’s a magnesium problem

    Could also be bacterial speck or spot. Look those up to compare. Not a whole lot to do if thats it except get a bacteriophage solution that may help it limp along. Ne t time move plants to a new area. Remove all plant matter and destroy (burn or landfill not compost). Im not positive it is speck or spot but looks like it. A helping point is it will often be on the tomatoes too.
