First Grow

By Looking a your pictures i whisk say definitely over watering , let it go a couple days without watering! Do the knuckle test each time before you water stick your finger in the dirt a couple inches and feel that the top couple inches of soil is good and dry before watering! This is good practice as drying out the roots good get plentiful air to the roots and they are able to breathe well. Repeat each time before watering and you should be fine! Good luck 🍀👍
