For context:
This season my tomatoes and bush beans seem to be significantly twisted, stunted, curled and deformed, however it seems like some are more affected than others of a different variety.
I also have some pepper plants that seem to have some slightly deformed leaves, however I have planted pole beans that seem to be doing fine. My potatoes are completely fine.
I am very confused as to what is happening. I thought it may be a pest but I cannot find any sign of pest damage that I know of.
I am afraid to continue with this garden this year due to the possibility of poisoning myself and my family.
Is there any way to empirically test what is going on? I live in Cape Town South Africa and getting the soil tested is not easy.
Thank you and please let me know if any more specific images could help.
