This is my second year trying to grow tomatoes on my balcony. Last year went alright but had some end rot on my romas. This year all 3 of my tomatoes have leaves that are turning brown like this. Can anyone tell what would cause it?
What fertilizer have you used?
@Custard to me it looks like sunburn. If u don't harden off your young plants by introducing them to the sun a few hours a day, then longer, etc before planting, they can get sunburn/sunscald. My fig tree got it this year when I brought it out of the garage for too many hours at once. Peppers can get it too. Keep watering regularly, maybe use some Epsom salt watering once in awhile too. New leaves will grow, the damaged will die. My 2 cents.
Soil looks pretty wet and the pot quite small.
