The first one looks more like M. backebergiana. If it was me, I would take them out of that peaty compost, clean the roots thoroughly from all remains of it (expect to loose a few or a lot of roots*) and plant them in a well draining compost. After that, you should wait a few weeks before resuming watering, carefully at first.
*sometimes peat clings to the roots too tightly and you need to wet them in order to remove all remains. If you go that way, put the plants aside for a few days, allowing the roots to dry and heal any wounds before potting them in dry compost.
