if its just on one or two leaves sometimes when leaves touch they for lack of a better word sweat and can cause some spotting on leaves if your rh is to high say around 62% and up

I water every other day, and feed every time I water in coco.

What nutrient line are you using, whats the recommended dosage?

coco is an inert medium, so in essence it is just like hydroponics.

if you are container gardening (which I'm sure you are) make sure every time you water, to get 20% run off or more.
