Tomato leaves curling and bright yellow spots -- is it blight?

Is this early tomato blight?
We have had pretty hot weather with no rain, but it has been a little humid, definitely not dry. I water the plants regularly, could this be too much water?
One in 4 has the yello, but they all have the curling leaves... Any recomendations?

Thanks!
Meyer

I don't think its blight or if it is I think its taking advantage because your tomatoes are missing either copper or calcium or both. I would try a foliar spray to correct this to see what works quickly and then amend the soil. Thats my best guess.

How can i amend the soil? I think it wouldn't hurt to add soil too, but it is pretty densly planted with basil under the tomato, i don't know how without smothering my other plant, do i need to sprinkle it or something?

I have the copper spray preparation, is it safe to use while the plat is setting fruit?

Thank you!

I sometimes make a soil slurry and water with it from a watering can with a long and narrow but wide open spout. That puts the soil slurry where I want it, and if it's stiff enough, or if the water drains into the soil readily enough, the soil component stays pretty much where I want it.

It's messy to do, especially if normal watering involves splashing about, but it works.

Also, topdressing is about quality, not quantity. Maybe try some really good and healthy compost to topdress it? Maybe mix in some finely crushed eggshell for the calcium? Maybe pee on them?

It is hard to say.  Could be several factors.  I am thinking nutritional and environmental stress issue, magnesium and hot days but some of the bacterial infections could come in to play as well.  In the end look at the totality of your situation and determine.  I hope this helps.

Here is some information.

Pee on them... Not a difficult task with my kids😜 we have other organic resourses too:, rabbit droppings ancd chicken waste on soiled straw (could those be helpful?) . They are already mulched with grass cuttings and I will crush some egg shells and throw them in.

I was worried to add to basil, cilantro and spinach ammonia from chickens and rabbits, should I for the sake of the tomatoes?

Thank you for all of those resources, i haven't had time to read through yet, but i will!
