I've got the same issue and I think it's damage caused by fungus gnats. They got out of control with my latest grow and my work schedule.. it's left a few brown spots on some of my leaves. I've eliminated so many other possible causes. It's either from the fungus gnats I had or its possibly a calcium deficiency but I don't think it's calcium.
