container tomatoes need constant water (daily in warm weather) and low dose feedings regularly.

if it is from YARD WASTES, it should be fine.

Question: Did you use just the compost, as medium or added something else to it too? What about the pH of that compost ? I am sure the people in that facility can tell you what it is and/or what can be done to improve it.

Soil pH is the most ignored thing among the gardeners. Luckily, most soils have an acceptable pH AND most vegetable can thrive within a pH range (6 to 7, 6.8 being ideal)

Stringy malformed leaves sounds like herbicide damage. I'd be suspicious of any compost from yard wastes unless I knew the people whose yards it came from. Did the city test it for herbicides (and other chemicals)?

I agree with ajsmama, it sounds like you have some herbicide residue in your compost. The unfortunate thing about yard waste from unknown sources is that there is a very high likely hood that some of them use something like weed and feed or other herbicides to control broadleaf weeds in their lawns. Since tomatoes are "broadleaf" plants and very sensitive to herbicides, they will show typical symptoms such as mishapen and curling leaves.

If you do a Google image search for herbicide damage in tomatoes, I am pretty sure you will see pictures that resemble your tomato plants.

Unfortunately, there isn't much you can do to correct the problem unless you want to go as far as repotting them in some clean commercial growing medium (not "soil" since you are growing in containers) after removing as much of the compost as possible from the roots. The drawback to that is it will probably stress the plants tremendously and set them back a lot.

Regrettably, this experience is probably going to have to go into your live and learn file.
