tops of tomato plants curling up

My tomato plants started out healthy but as they grow out of the cages and are blooming, the tops are getting spindly and the leaves are curling up. I planted them where I had pile of horse manure all winter. They started this after some 90 degree weather. They had plenty of water and were sprayed for insects and disease. Thanks for any suggestions.

There can be a few reasons for leaf curl on tomatoes.
The hot temperatures may be a part of the issue. Uneven watering also may add to the issue.
Horse manure generally will break down in 2 to 3 months and makes great compost. You do need to look and smell to make sure. It should look like soil and not have a manure odor.

Here are a few links for you.
