Tomato leaves burnt. Disease fertilizer burn or both?

So I have a feeling that I have over fertilized the tomatoes.

I bought some high nitrogen high-quality soil and then proceeded to add a cup of kelp and bonemeal into the bottom of the hole, put some crushed Tums on top of that For calcium and then some rock phosphate and put the tomato directly over that. Which was pretty stupid but I did it and now my tomatoes are burnt. I've been flushing the smart pots out for the past few days I was doing it morning and night but now temperatures are low so I'm just doing it in the morning. Some of the spots on the tomato plants don't look as bad though and I'm wondering if it's all nitrogen burn or if there's some disease affecting them as well? I just potted them in the pot and it came on pretty suddenly after potting them up. I'd say two days after potting them.

I hope they will recover as I know tomatoes are hearty but I might've well and truly fucked them up. Any thoughts?

If you look closely at the photos you'll be able to see more in depth when I'm talking about.

I'm sorry that happened. If you layered that stuff down there, I would carefully dig up the tomato plant, remove it all and replant. When I use bagged potting soil with added nutrients, I don't usually have to fertilize more than once a summer. When/if I do, I use a well balanced fertilizer with micronutrients at 1/2 strength.

The biggest problem containerized tomato plants have is blossom end rot, caused by calcium deficiency. But, the deficiency is not due to a lack of calcium in the soil but a lack of available calcium to the plant. If the potting soil is not kept evenly damp, tomatoes formed on the dry days will have blossom end rot.

Using high nitrogen in tomatoes will grow some nice bushy green plants but not fruit. That's why I let the experts formulate the fertilizer. All the stuff you added (if mixed into the soil) might be a good idea out in your garden but, container gardening is a completely different tiny micro-environment where the slightest change can have some pretty radical results.

Ok. I'll try to scoop it out. Do you think there's any chance they'll recover? I did this with 15 plants.

I hope so. Tomatoes are pretty hardy.

Well I scooped out the ammendments and rinseD off the tomato roots So hopefully they improve. Filled around them with new soil. The weird thing was some of the Tomatos with no scorching had fertilizer right in the roots, and some that were all burnt up had ammendments an inch below them. I wonder why it affected some of the plants so intensely and some were barely affected (so far).
