Please advise on Yellowing on tomato plants.



What kind of yellowing, Malcom? On older plants, it is normal for the oldest leaves to turn yellow, but that is rarely more than 10% of the foliage. More extensive yellowing is usually a sign of nutrient deficiencies, or watering problems--the exact appearance of the foliage is a clue to the exact problem.

Use proper tomato food to feed the plants if you're not already - that contains the right amount of potassium and magnesium. Otherwise, as Tugbrethil says, need a photo or more info.
