Can someone give me advice please. I’m new to Thai constellations, well monsteras in general. On the right is my Thai when i first got her and in the last two weeks she’s been getting these brown spots. I cut it off three times and it keeps coming back. I don’t think it’s a watering issue because i have her in a clear pot and water when she’s 75% dry. I would chop the leaf completely but she is working on pushing out a new leaf. Any advice thank you in advance !
