This is my 3rd attempt at basil on my AP system. 1st was purchased and the other 2 grown from seed. After a couple weeks this black spot infection seems to appear. It also happens on the ones I left in soil. I really love using fresh herbs from my system, and want to add basil to the mix! Any ideas?
What is the best way to treat the affected plant. sounds like it is systemic, (if that is what it is....) Do you know what causes this mold.
