Sorry if you feel you're being 'told off' ... that's not our intention .... but you did ask what we thought was wrong ...
To check whether it needs watering, I recommend the 'Finger Test' ... stick your forefinger in the soil up to the first joint. If the soil down there is dry it needs watering.
Give it a good soaking, several buckets full, keep watering until the water is running out of the drainage holes in the bottom (it has got drainage holes? ) and let it drain.
Do the Finger Test every day, but don't water again until the soil is dry at that level.
