The leaves of my coleus have been going limp. A few days ago, I noticed that the leaves were limp. I guessed that I probably hadn't given enough sunlight but the leaves were back to normal when I woke up the next morning. I have never had this issue before. I got my coleus about 6 months ago.
At 1 PM today I noticed that the leaves were limping again. I gave it a little water, gave it a lot more sunlight, and by 2 PM it was fine again. So naturally, I assumed that it was because of not enough sunlight but it still doesn't make sense why it would be fine overnight last time this happened.
Some other information that might be useful:
- I water my coleus daily, every morning to the point where the soil is moist enough. And throughout the day if I see that the soil is entirely dry, I spray some water.
- I don't use fertilizers.
- I live in Tehran and pollution is a huge problem. It has gotten a lot worse these days. here is the AQI. I'm not sure if it has to do much with the state of my plant but I thought I'd mention this just in case.
It is winter now, and some might think that my plant is getting less sunlight because of it but in winter here there's still a lot of sunlight.
I have uploaded some photos here. They are all from today, before and after the issue.
The average temperature during the day within the past two weeks in the city has been 8 degrees (c). I'm not sure about my room temperature but it has not changed and I had no problems before. I use a radiator in my room that's below the table on which my plant is.
