remove the spotted leaves.............wash your hands.....trash the leaves in a bag..........ph should be 6.0-8.0 it should be planted in the ground....might be a fungus.................put mulch around the bottom leave room for it to breathe. Something might be eating the buds.............after the sun goes down & the plant cools off mix up 2 tablespoons of dawn & 1 qt water and spray it..............get the buds good when they start............try to get under the leaves..................Happy summer.
