My eggplants have developed a leaf problem.They have a linear to circular pattern on the top side of the leaf-the pigment is gone, after a while the leaves start to curl slightly. These are month old plants grown from burbee seeds in potting mix, recently moved to a scrren porch-to harden off, no sign of bugs. One pepper seems infected too-i suppose because both nightshades? Do yoou know what this is???? Thanks, ken
