    Powdery mildew. Can treat with suffering, mancozeb or a milk/water mix.

    Looks like powdery mildew to me. Remove all affected leaves. You can spray the rest with 50:50 milk and water, the bacteria leftover when it dries usually outcompetes the mildew but you have to spray every 2 days for about a week. And keep carefully removing leaves with white spots. Give it some seaweed for stress if u have some, might do better in a more open area where it’s less humid if possible, even up on a table will help
