Hi,
I got my first bonsai a month ago and It started losing leaves for two days. It lost seven leaves yesterday and four ones today. I'm a little concerned and today I added some egg shells in soil since I heard its calcium would help.
The leaves look healthy and I'm afraid it's dying. I attached some pictures. It's what happened in last few days, so kindly please let me if you think any of these could be a reason:
1. Five days ago I added two neighbors, one of them is Coleus, can they fight with my bonsai?
2. Two weeks ago I built a wooden plant stand and while color looked dried then, I can still smell color.. May I hurt it by putting it in stand?
3. Five days ago I placed a lampshade in stand. It's about one meter far from bonsai, has 5 watt yellow LED and no direct light come from it to bonsai. Can it be it? I already decided to not turn it on anymore..
4. It's a week weather is cloudy and there is no sunlight.. I'm afraid, I can't do anything about it :\
5. My place water is a little hard.
Thank you in advance for putting your time. Any comments are welcome.
