FIRST TIME AGAIN DUDE

She does have a little bit of yellowing, This could be from to many nutrients( not sure if your adding any if so use just water for the next couple feedings ). I think its slightly over watered and that is causing the color. The roots start to rot from a lack of oxygen. Your soil looks really compact. I would recommend adding perlite to your soil mixture when you transplant to a larger pot. When you water you want to let your soil completely dry out before watering again. Happy Growing
