Plant issue

So i am a new grower and i am having an issue there are some spots on one of my plants and all the pictures look similar to what I am dealing with so im not sure what to give my plant please help. The pics are from lower on the plant.

Thanks

it wont be about adding anything likely, but about taking something away.
lower leaves always die off this way, some will call it a deficiency, you'll add something, and that add will
cause more issues for you. If the rest of the plant is swell ...relax
follow the directions on your nutrients, dont panic grow organic

picture of entire plant would help
