This is very likely a mosaic virus. Many grafted plants are being created without proper disinfection. I'd keep it away from your other plants for now. Absolutely do not use the same cutting tools. I have been dealing with these same symptoms.
All efforts were made for nutritional deficiencies, pests, etc. Then I found that my adenium nursery had thousands of sick plants that were imported from Thailand. They exhibit every textbook symptom of mosaic.
