I have had my bipinnatifidum for about 6-8 months and decided to put it out this summer. I live in zone 5 so it started doing really well. It grew out of all the old leaves and started getting big. I have it in a 12-gallon pot with fox farm soil and nice drainage. I have recently noticed scattered yellowish spots on all leaves, when the light shines on the back of a leaf, you can see a lot of the damage. And the back of the leaves looks like something was eating it, Iv never seen any kind of bug or mite on it. I'm concerned about the expansion of it, it seems like the damage just keeps spreading. Does anyone know what's going on and how I can fix it? Thank you! I appreciate anyone who can help or has any info!
