My tomatoes , peppers, eggplant and sunflowers are showing signs of herbicide damage (curling, puckering, feathery leaves and stunted growth). The tomatoes are stunted, the lower leaves are getting bigger and tougher and the top leaves of the plants are curled up and sort of shriveling..they are starting to bloom, maybe because I fed them some Fox Farm Grow Big plant food! This year I got some llama manure for the first time..and I used a lot of it..thinking the more the better, etc. Is it possible to save the plants? Use seaweed/kelp to dilute the poison? How long will it stay in the soil?  I'm so bummed. I have a friend who got some of the same manure and he's got the same problems.
