What Could Be The Cause For Malnourished Tomatoes?

[tribie]

Some tomatoes in my mother's garden are more yellow rather than deep orange. We have made a joke about it and called them malnourished. The funny thing is, the others are deep orange. All of the tomatoes came from the same seed pack. Are they sick?

Not necessarily, there are a number of possibilities: mixed seed in the pack. a slightly less favourable position, natural variation, variation possible with F! seed.
Undernourishment, however, is both most likely, and the only problem which you can remedy, so an extra feed of tomato fertiliser is about your only option, and should do little harm.
