Oh wow that's a bummer, but I agree with shov.
Make sure you don't over water or under water. I give my plants water until I get a little run off from the bottom. Then let the soil dry out until I water again. And I would also recommend transplanting them from the terracotta pots into bigger plastic pots. The terracotta soaks up a lot of moisture and the root system will grow into the coarse surface. So if you wait to long to transplant you will lose almost all of the roots in the process. Best of luck to you. Peace.
