I looked at the leaves they look like they got a virus , but not the Tobacco Mosaic , sometimes it happens to the best of them man every plant on this planet catches virus's . There isnt much you can do about it its just something thats going to happen . Some plants are more susceptible to it then others even some of the same strain . Just keep an eye on it and remove the leaves as it happens . Even if you left the leaves it wouldnt do any harm to your plant infact at the end of your plants life cycle might even look cooler cause it will have some white in it haha . I hope this information helps you understand that virus's come in all shapes and forms and that when it comes its just really an "abnormality" some plants are even bread to have virus in them like lillys and other flowers . Other then that your garden looks like its rocking and rollin . - Happy Growing!
