Jade watering

Jade watering

I have killed jade before by overwatering it and I now have three jade plants that I recently propagated. I don't want these to die and I am wondering if anyone knows any telltale signs of overwatering? I have noticed that two of the three have an underleaf tint that is reddish and I am wondering if that means those two have had a little bit too much to drink. Any suggestions? Thanks
