Answer: The clear round balls are probably water droplets with plant carbohydrates mixed in. When plants are growing quickly and water is abundant, excess moisture is forced out of natural openings in stems and leaves. The sugar content keeps it from evaporating, resulting in little droplets that remain until they dry out and fall off. Curling, brittle leaves can indicate overwatering. Remove the affected leaves (just in case there's a disease lurking there). Your plants should recover once things dry out a bit. Hope you have a bountiful harvest!
