Tomato Leaf Marking / Spots - what's causing this?

Have some markings on the lower leaves of my plants. Is this mold and/or blight? These are just here and there on the bottom 2ft of the plants. Oldest foliage.

Otherwise these are doing well for starters put in the ground on June 7th. Tallest indeterminate plants are 8ft now.

Wow! Very nice garden! Everything is looking good.

What has your weather been like? The leaf curling in the middle picture is physiological leaf roll. It is the plant's adaptation to hot, especially hot and dry, weather. It helps the leaf conserve moisture.

None of what you showed looks like blight or mold. You can make gardening stressful by worrying about every minor color variation or tiny spot. Nothing in nature is perfect. Your plants look very healthy.

Thanks for the reply! Good to know on the leaf curl during hot periods.

Re: Tomato Leaf Marking / Spots - what's causing this?

It looks like sun scald as well as the leaf roll. I don't think in Vancouver you need worry too much. In southern areas growers will install a sun shade material like netting to protect against the bright sun. Only on the hottest, driest days would I consider sun shade even here in the mid west. You should be OK.
