Thanks for the update, love the structure on Johaar2 #11
Might be too much nitrogen the curling
I was going to say nutes too. How often do you use the Epsom Salts? Your soil may be very salty. With all the yellowing they need more N. When you see the tips curl down just slightly you know that N is going low. Over watering does that too so check both those things.
Do you have access to blood meal? Top dress with it a couple times a week until things look better. You can do a 1/4 teaspoon at a time until they come around. Either that or dont dilute your tomato ferts. Use it at full strength but dial down the amount untill you get a better feel for what is going on. You will only need the N for a few weeks more depending on flower time. I cut it half to 3/4 of the way thru depending on how the plants are looking.
You might also beef up the P. It will help bulk up the buds at this point in the grow. Also I think you really need to repot Even just a slightly larger pot with some fresh soil could help.
did you compost the soil when you added the blood fish and bone? When mixing that stuff in to soil it has to sit for 30 days. Otherwise the composting action burns up the roots
