If that’s just the bottoms, I wouldn’t worry—- looks like there might be soil on the underside of the leaves? Flip them and make sure you don’t have spider mites.

Yellow and purple leaves
I stopped feeding beginning of the week because I had yellow tops on one of my buds. I think it is causing yellow leaves. Does that sound correct? Also I am seeing sort of a purple colouring on some of the leaves. Is that okay?

Yellow marks in leaf center and weird King Kush?
There seems to be some yellow marks developing in the center, this tends to be on the outer side of the leaf, especially during over/under watering? Could this be calcium/magnesium deficiency being that the water source is from reverse osmosis? Also, any thoughts about the KKush?

Super soil needs activation?
There are plenty of nutrients in my supers soil. However I heard that the problem might be that the soil isnt "activated" is that logical? Thus need to add organic ferts? I am trying this, but I'm sure the super soil has months of nutes in it!
