Your calla lily may be getting too much water, or it could be going dormant. These plants do thrive in soil that is kept evenly moist, but they can be over-watered. The best way to know if its time to water is to feel the soil – if its too wet you can squeeze water out of a handful of soil, if its too dry, it won’t hold together in a loose ball when squeezed. If this plant bloomed already, it may be going dormant (yellowing and dieing back to the ground). If this is the case, you need to be careful not to rot the underground bulbs with too much water. Here’s a link that may help; follow guidelines whether planting in a pot or outdoors.

My calla lily has drops of water coming off leafs and flowers why is that
It’s ok. This process is called guttation. Calla lilies cry before the rain and when you watered them more than they need they just get rid of it in such way. You can find more information in the internet.
I am more concerned about those wavy leaves, as for me it looks like the virus….strange lines of light yellow and the shape too…I am not 100 sure but may be someone can explain why they are like these…have the same problem with mine.
