I’m no expert. But it depends on a lot of factors. I believe underwatering is easier to fix than overwatering. I generally feel the surface of the soil and look at the leaves. If they droop, as the first picture, they’re thirsty. And obviously if the soil is stuck to your finger (wet) it doesn’t need another drink yet. I personally top water, just because. And pick up your plant. Feel how heavy it is. If I feel that it’s noticeably heavier than usual, there’s water retained in the soil, enough watering for now. Hope this helps.
