deff looks like a case of overwatering. it doesn't look too terribly bad but it deff needs to be pretty dry before you water again. I recommend watering based on the weight of the pot. its a much more accurate way to judge how wet the soil is. basically when you next water the plant pick up the pot and feel the weight. now every day, when you check on your plants, pick them up and feel their weight. when the pots are dry enough to need water they will feel significantly lighter than when they were still very wet. this is the easiest way I have found to water plants in soil and not worry about over/underwatering.
good luck! if you have any other questions or just want some friendly advice feel free to dm me!
