My newly grown pole beans have developed a series of white patches in the leaves- seem to have been there when the leaf was growing, so the sharply defined borders can be puckery. I have thought of leaf miners, but the patches are broad and not trails as I’ve seen in leaf miner damage in the past. Any ideas?
