I have tomatoes,cumbers young plants in my green house. They seemed to be OK at first then because of the cold snap I put a greenhouse paraffin heater in. One plant has suddenly had edges of leaves turn black and wrinkled although it still seems to be alive., Could the heater fumes to have caused this. As it was a new heated there was a strong smell at first. The other plants are fine should I get rid of this one will it be all right the eat fruit. I have not used heater since.
