One of my plants has these rust colored spots on older foliage. Not all the plants have them. Just two plants currently. I was thinking fungal infection but rubbing it doesn't leave my fingers stained and doesn't leave any residue. New growth on top is green and fine. I have 2 other cultivars going that don't have these spots and are in the same soil set up and nutrient schedule.
Plant info: durban poison. Week 4 veg currently. Grown outside. Currently being fed cultured biologix dr. root, dr growth, and grow 360 at 1/4 strength and watered with pH balanced purified water. Spots appeared after a few days of heavy rainfall.
