My monstera Thai con has a tiny brown dot (~ 1mm long) and two brown lines on either side of the sheath part or the stem (~ 1cm). Is it due to humidity? Or is the grow light too strong? (It’s 10W, she’s getting indirect light from it). 😬 I know it’s small but I’m hoping if I catch it now, it won’t turn into a bigger issue later on! 😭🙏
