I just got a kalanchoe fairly recently and it was very healthy when I got it. We put it into a pot and it was just fine for a week or two and then the leaves started to become a bit soft so I figured it was time to water it. When I watered it the leaves felt better for about a day and then went back to being soft. I noticed that the soil was drying out very quickly (almost completely dry that same night). I thought it might be due to heat or too much humidity so I tried moving it outside and it got even worse. I left it alone for about a week and watered it again today but I am confused as to what to do or whether its being over or under watered. The leaf colour is darker green but more dull than it originally was and the leaves have little wrinkles on their ends. It gets plenty of light on an east facing window. After watering it the first time, I repotted to a terracotta pot so that it would get better drainage/dry the soil out faster just in case I overwatered it. It seems like all information online says that it's very difficult to under water kalanchoes but that seems to be the problem in this case. I am just worried to keep watering it and kill it. Anyone have any input to help?
Here is a picture of the leaves drooping, and they bend very easily.
