If you see any brown spots on your plant, don't worry! There are probably just a couple of things that could be causing this. 1. Is it getting too much sunlight? If so, just move it to a spot where it'll get some indirect sunlight. 2. Or maybe it's a little buggy? If so, just find the part that's affected and give it a quick spray with an anti-pest spray. I'd suggest cutting the part with the brown spots to help it grow new, healthy leaves.
