Tomato Plant Grey Spots on Leaf/Stem?

[Bryan24681]

Hi,
I hope this question hasn't been addressed too many times already but from my research i haven't found an answer to this yet. I have a younger tomato plant that has developed Grey (appears to be fungal) spots on the leafs starting from the lower ones and working they're way up. Today i noticed that that it has now spread to the stem. Can anyone help me with a diagnosis and potential treatment. Thanks!

Looks like powdery mildew to me.

Thanks!

You might look into liquid silicone as used in hydroponics. Also, having fought that issue myself, I have become a fan of thyme oil agricultural products. Thyme oil and garlic oil have some amazing properties for usefulness in the garden.
