I did not fertilize it lately as it was winter here. I was definitely overdue to fertilize it so I did yesterday. 😊 I hope this will solve the issue or part of it. I looked up the manganese deficiency on google and it could explain the shape of the leafs (the waves on it) but would it also leave some type of white dust on the leaves? If you look closely at the pictures, you can see some very tiny white dots(1-2mm) on the leaves and some are in concentrated areas. If I wipe it with a wet cloth, it goes away like dust but comes back shortly after....would a manganese deficiency cause that as well?
