I have a lime tree inside behind the window in a pot. It's got a couple of fruits on it and it seemed to happily grow new foliage up until about 1 month (or so) ago. I also stopped watering it a few days ago as I thought it wasn't as thirsty anymore i.e. the soil would stay moist and not dry out. What could be the problem here? When I shake it, it doesn't drop any leaves. but also it doesn't have a whole lot of foliage on it...
The leaves on the bottom are rather new and on the branch on the left side, you can see a fruit, the largest on the tree (there's three smaller ones), too.
I tried to take another picture to give you some better context but it's difficult as it's nice and sunny out.
When watering it, I've been using a fertilizer that contains:
- Available Phosphoric Acid
- Soluble Potash
Is that okay, should I keep using it or use just water or a different fertilizer?
