Hello. I was wondering if I could get some help. I woke up to find these spots covering alot of the leaves of my sweet basil plant. It\'s an outdoor plant. We\'ve had an even mix of sunshine and rain. Lately I\'ve started watering the herbs with a spray nozzle for 5 minutes straight on days we have no rain. I noticed the spots the morning after I watered the herbs the previous evening. I have a feeling I\'m doing some gardening no nos. Does anyone know what these spots are and if or how I can save the plant? Thanks!
