Hi, I would be more concerned about the african cichlids than the plants. Last year i was growing plants with a KH of 7 and GH of 9 without problems. GH of 11 is not such a hard water, it's more low-medium hard from my point of view.

You can do a research, some plants will prefer such parameters, other will not but will grow in it nevertheless, maybe slower.
