I can't figure this out. All of the other tomato plants I have are growing nicely except for this bunch of tomato plants. They're starting to turn brown and the leaves are curling inward. The blossoms drop over time as well.
I need to know what's stressing the plants. I planted all the plants in the same soil too. Could it be a mineral problem.....it's been really hot here too (lower to mid 90's). I water them twice a day because it's been really dry here.
