hi folks, I hope I am in the right form to ask this. From the ages of 18 to 21 I worked on vegetable farms, but I haven't really gardened since. I built myself a nice raised bed this year and grew some tomatoes for the first time in five years. My disease ID chops appear to have atrophied considerably, because I don't really know what's going on with these guys.

I have two Speckled Roman, one Mortgage Lifter and one Sungold plant thriving for the most part and setting nicely sized fruit, but there's something going on with the foliage.

I have attached pictures. Was mostly bottom leaves at first but has now started happening to leaves midway up the plant as well. What do you think it might be?

It looks like an early blight. The best way to combat blight is prevention. Keep the bottom leaves from contact with the soil, water evenly and at the base of the plant rather than overhead watering. I would remove the affected leaves and put them in the trash rather than a compost pile.

Good sanitation is key. At the end of the season remove all vegetation from your growing area. A mulch program to reduce leaf contact with soil is essential since most leaf disease is soil borne. Strong, healthy plants combat diseases. Good airflow at the base of tomatoes will resist disease as well. Good basic growing practices are your best bet.
