i poured some for my passion fruit plant as well, apart from using fertilizer for flower/fruit. now it's fruiting like crazy.

Any succulent experts here?

I bought a succulent plant 2 Sundays ago and has only watered it once since then. I noticed that few days after watering, one of the leaves is starting to turn yellowish.  Based on Google, this means it is over watered. I'm wondering how that is possible as I only watered it one time and I made sure the water drained out. 

I've had many succulents died on me in the past so I'm wondering where did I go wrong again this time.  The pot is in a shady spot.

Anyone has any other tips to prevent the whole pot from turning yellow?
