UPDATE: Found some white dots that are extremely tiny. Not sure if they are scale or mineral deposit from water. The palm plant has also closed all of its leaves.
My palm plant was doing great and was quite stiff/upright. I re-potted it into another but better potting mix and it loved it, as it got even more upright. However, it suddenly started drooping. Now even after watering, the plant is going sad and not happy. I don't know what to do. I have moved the plant now to even more brightly-lit indirect lighting but no improvements. The soil drains very fast and the pot has a drainage hoke at the bottom.
