Why are my tomatoes leaves going brown at the ends,,just shrivelling up a bit, and one of the trusses is going the same way, I have been growing them for 40 years and never seen this before. Can anyone help?
This can happen with both over and under watering, shouldn't be too serious, just determine which it could be, as you've been growing them for so meny years, you'll know what the remedial action is, and just cut off the bits that have gone brown, possibly also, some Epsom Salts might help.
mine did the same and i was told it was because when i watered them in the hot sun the leaves were being scorched. best to water in the evening or when its not hot sun.
