Tomato leaves spots, yellowing, dying

Question: Attached are pictures of symptoms on my tomato plants. All 30 plants have this problem. It is mostly on the lower branches, which I cut off (I had cut several of the  bottom branches as soon as the plants were established. The middle branch in the phot with three samples shows the underside of the leaves (with spots). Is this Septoria Leaf spot, Early blight, or bacterial spot/speck or something else? The entire branch eventually turns all yellow and can drop off.

I recently cut off all the diseased branches I could see and sprayed with copper fungicide.

Tomatoes were grown in this same garden last year, but there are not other places to move the garden where it will get enough light.

I have the entire garden covered in 20-year landscape fabric (plants planted through it), a drip tape irrigation system, and trellis/fences to tie the tomatoes up, so they are not on the ground.

response: The symptoms are a bit challenging to diagnose (many early-stage tomato diseases and environmental stress symptoms can look alike) but they are most likely Septoria Leaf Spot. You are already taking the right steps to suppress infection, so continue to monitor the plants and feel free to send us additional photos if they change notably or worsen. Follow any instructions on the fungicide label about temperature restrictions (many sprays should not be applied while temperatures are above 85 degrees to reduce the risk of plant tissue damage) and when to make repeat applications, since one dose is often not sufficient by itself to suppress disease all season.

response: Thank you for your help.   So now I believe I have blossom end rot on my ripening tomatoes (picture). It is affecting more than one tomato variety.    I attached a soil report from this year. You can see the calcium level in my garden is too low. . I did make amendments to it last year, based on a soil test, but apparently it was not enough (I tested again because I wanted to see how well the amendments worked, and some did)   My garden (picture) is covered with landscape fabric so amending the soil will be difficult at this point. I know (from AAS lab) that calcium is related to watering, but I have a drip irrigation system, and watering has been pretty consistent.    Can I use foliar calcium (e.g. Rot Stop) to bump up the calcium in the plant? There is a product called Cal Mag that everyone raves about but this soil test does not show magnesium deficiency. Thank you. Meg

response: Hi,  We are checking with our vegetable specialist and will get back to you after the July 4th holiday in a few days. Some of the tips in this brief web page about Blossom End Rot on Vegetables could be helpful in the interim, although you may already have this knowledge. -Emily

response: Hi- if the BER is widespread you can try the Rot Stop. We also suggest applying 1/4 cup of gypsum around each main tomato stem and work it into the top few inches of soil with your fingers. Jon
