I am about to post another question and realised that the message I typed on my phone to thank you all once again never got sent
Just as an update, my African violet is doing great! I cut all of the spotted leaves following the recommendations of one of the gardeners I called, who was kind enough to give time to my request and he said it must be a virus and that this is what I should do. If this ever happens to you guys, you know what to do
So maybe you were right Daisy, only things is, there were not thrips, but would they be very visible?
