# Hi all, My plants were doing great. But recently, I am spotting these…

_Posted by Adrija on 2026-01-16_

Hi all,  
My plants were doing great. But recently, I am spotting these brown marks on one leaf and the other leaves are turning yellow. I reduced watering because the temperature is low (5-7^C outside and usually 16-18^C indoors). I use yellow lights because sun had been hiding constantly 😑 But they are right next to window, so whenever there is sun, they get it. They are potted with Miracle grow tropical soil mix and perlite.  
I checked the roots and they seemed healthy, some white roots too.  
Any suggestions to help them survive? Soil change?  
Will appreciate any suggestions. Thanks!

I’d check that they’re in a pot that doesn’t constrict them too much. Especially if it came on slowly. Maybe check to see that they aren’t root bound

Have you checked the leaves closely for pests? I had the same problem (mine was with a pothos) and it turned out to be spider mites.

Oh God! You are correct! I checked and I noticed some white tiny tiny mealybug! Thank you so much for the advice; I hope I can save the plant now.
