I discovered some brown spots on leaves....please tell me that this not root rot 😨 Some leaves that looked worse had been removed last week, I thought that this was just a nutrition issue.

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.
