I have a coffee plant; I don't know the exact variation but I think it's "arabica". I got it as a small plant in a foam coffee cup 10+ years ago. It's currently located on a wall facing an East window. The plant is 10ft away of the window. I water it twice a week: on Mondays and Thursdays.
Recently I started to use a 6-4-6 fertilizer to help it grow. But as always when I use fertilizer it start to loose a bunch of leaves (see attached 2 photos).
Also you can see long branches with leaves only at the end which don't look good (it use to have leaves all the way but they all fallen).
What can I do to help my plant grow? Should I do some cuts?
