it sounds like root rot. i would suggest starting another grow and make sure to clean everything that the plant was in, esp. the pot. when you start the new grow, make sure to not over water for the first few weeks, i would also suggest keeping them in the solo cups for 3 weeks or start them in a bigger pot and leave them in there. this save any time from transplanting, and stress caused by it. hope this helps

Dont let your soil stay soaked just damp. If your worried their falling over and croaking, it's called damping off, try sprinkling a little cinnamon around the girls and water in. If it's not to late this could save her. Dont start feeding as they need to adjust to the nute levels in the soil. Cheers
