Hello. I know i have been posting a lot recently about the health off my plants but I have another problem; My Swiss cheese plant is yellowing and it has brown areas. As you can see in the photos, it has some leaves with crispy brown edges and some with soft brown spots. The soft spots are newer - I just noticed them today. I looked up what might be causing the yellowing but it was very vague. I recently watered it so the soil is still a little damp on the top. It is about ten feet from an east facing window that has sheer curtains. The temperature is usually kept to 75. Please help!
