u/D-LAWE

Hi there, had this plant for a year or so and initially had 3 leaves. Took forever to get a 4th established and managed to get there a couple months ago. Now there is a 5th but one leaf is turning yellow. Wonder what routine you usually use for this plant? Is the pot large enough, what soil, fertilizer etc?

I usually water with water and every so often put a bit of fertilizer inside…

General opinions welcome!
