Plants.....?

I have had a problem I am growing some tomato plants and they have started to die on me. I think this was deliberate can anyone tell me what would kill a plant that's in a liquid form and is also odourless

There are a bunch of chemicals that can kill plants. I would assume a lot of different cleaning chemicals and even household salt could kill a plant.





But why do you think someone killed it deliberately? Bugs and animals are also known to kill plants (climate as well). There are a lot of factors to consider, but I highly doubt you will ever find out what chemical it was or who did it without the help of a specialist.
Reply:Too much water? Lots of random chemicals.
Reply:over watering can kill a plant.
Reply:Probably any number of things. Salt water around the roots is one thing. If it got sprayed with roundup or the like you'd probably not know it until it died. Interesting you think it was deliberate. Did you do something to someone that may be trying to get back at you?
