Under or Over Watered?

I noticed the leaves curling in a few days ago so I gave it a bit of water on top. I have a moisture meter and the soils reading as dry. But when I gave it that water a few days ago it didn’t perk up, making me think it was over watering? But now I’m thinking it’s under watering because the soil is dry, at least I think (when I put my finger in, it feels cold so it’s hard to tell if it’s wet or just cold, no dirt sticks to my finger so I think it’s dry)

Also, what’s the recommended watering method for a satin pothos? I live in a drier climate so I feel like the soil doesn’t dry out very fast. Should I:

1. bottom water until fully saturated

2. Bottom water, but not long enough that the top of the soil is wet

3. water from the top a little bit (not enough that it drips out from the bottom)

4. Water from the top until water drips out the bottom of the pot
