I don't think that they are dieing - but I do think that they have had just a bit too much watering ... and have a look at the pH of the run-off when you next water them, but let them dry out before you water next.

Yo giving her/he to much water.

i agree...over watered. you need to let the soil dry out a bit between watering then water til there is a good run off! overwatering is caused by watering like every day instead...when you should be watering every few days...and ph is important too! do you test it?

Small pot, water twice every 2-3 days, usually in the morning since they love their breakfast, and after the day. Use a 350Ml bottle and water it with that.
