Some of the tomatoes are doing....this. the leaves are withered like and crunchy. Not all of the plants, a number are doing just fine. The leaves in the photo are wet because it just rained although it has been extremely hot the last few days here in NJ. What silly thing am I doing wrong? Thanks!
It might just be that they dried up in the hot weather. If so they'll uncurl now it's rained.
You might also want to check for ants breeding black fly on the underside. They suck the moisture from the leaves causing them to curl over. You can usually just scrape them off with a wet finger.
No insects, so maybe it's just the very high heat for here! Thank you!
