Hello! Hope, somebody will help me. Before ten days I've got a great hardy looking Silver Coral - Senecio Scaposus succulent. And day per day he's got weaker. The leaves started to droop, wither and finally shank off. The youngest leaves in the middle seem so dry and others the biggest ones seem like they're overwatered, though I've watered only one time, when the soil was fully dry. Now I have no idea what's happening with my love. Maybe someone has some tips how should I act now? I'll be thankful for who gonna help me. (In the comments you can find pictures...)
