Hello, drooping leaves is normally over or under watering, over watering the leaves droop and under watering the stem will droop with the leaves. I see that your soil looks very dry around the outside, if you only wet the soil right at the plant it will not stretch it's roots out into the rest of the pot this could be the problem. You don't have to water the entire pot every time that could cause overwatering but just moisten the whole thing before you put the plant in it then just don't allow it to completely dry. Roots won't grow good in dry soil
Hope this helps you out
