Good morning Gardeners!
I have 8 vine tomatoes, in 10" pots, 2 Ruby, 2 Chocolate Cherry, 2 Gardeners Delight and 2 Galina. One of each on the left hand side of the greenhouse, and one of each on the right. All looking good apart from the fact that the lower leaves on the Galina and Gardeners Delight plants on the right hand side are going yellow - the top leaves and flowers looking healthy. All plants have been given exactly the same treatment, so could anyone out there offer any clue as to why only these two plants are affected ... and probably more important - by what?!
