Why your jade plant has brown leaf and spots?

yes they will go away after a few months if you do the right things. you should not water it too much that may be causing it water when soil is dry and more so in summer than winter take the plant outside it the summer and leave it inside in the winter to protect it from frost. also see if there is very small red Spiders or grubs in the soil that will also cause it to have the spots.

hope that is helpful!
