BAD NEWS FOR YOU MAN I'M SORRY. YOU NEED TO UNDERSTAND HOW POWDERY MILDEW FORMS. LET'S GO INTO DETAIL... OK... FIRST OF ALL POWDERY MILDEW IS A DISEASE. A FUNGI OF SOME KIND. LET ME GO TO THE BIBLE...
THERE IS A PICTURE OF A PLANT THAT HAS THIS SAME PROBLEM, IT SAYS "POWDERY MILDEW, FUZZY WHITE SPOTS SIGNIFY THE DISEASE ALREADY PERMEATES THE ENTIRE PLANT. CLIMATE CONTROL WILL PREVENT POWDERY MILDEW.".... THE DISEASE IS IN THE PLANT SYSTEM AND GROW OUTWARD, IT IS OFTEN FATAL AND CAN DESTROY AN ENTIRE GARDEN. IT SAYS TO REMOVE AND DESTROY ALL AFFECTED PLANTS AS TO NOT SPREAD THE DISEASE.
THAT'S TOUGH MAN, THE CHOICE IS YOURS BUT I WOULD AT LEAST SEPARATE IT FROM ANY OTHERS YOU MAY HAVE. GOOD LUCK. OH, IT RECOMMENDS TO USE A PRODUCT CALLED "SERENADE", IT'S A FUNGICIDE (BACILLUS SUBTILIS) NASTYRUDEDOGG IS HERE TO HELP.
