Hi Ed,

Thank you for contacting the UVM Master Gardener Helpline and providing excellent photos. Kudos to you for selecting varieties of tomatoes are very flavorful!

I consulted with Dr. Ann Hazelrigg who is the Director of the UVM Plants Diagnostic Clinic and she diagnosed the white spots/brown spotting as an abiotic injury associated with cold damage. An abiotic injury is an issue caused by environmental conditions and not a pest or disease. Either the plants were subjected to cold soils or cold temps. There is no need to worry - the affected plants will grow out of it just fine. Regarding the weird discoloration of the leaf, it is a genetic abnormality. Some cultivars are prone to this and it is not certain why. Luckily, it does not affect the health of the plant.
