Hi Can anyone advise on why my young tomato plants have a yellowing tinge to the leaves and what can I do
12/04/2013 at 11:46
How big are these plants? Are they in small pots? It's still early for tomato plants at moment.

It's not necessarily too early providing they're kept warm with plenty of light.

CLER, is there any chance of posting a photo? In the meantime, what size are they? Do they have real leaves? Yellowing of leaves on a young plant can be a sign of overwatering but also of insufficent light. Or even both.

as a new gardener I admit my enthusiasm got the better of me and I have probably sown my Tom seeds too early because of this awful spring. my plants are about 6inches tall in 3 inch pots yes they loook strong enough but a little green around the edges !!!!

Am I right in thinking yellow leaves can sometimes be a lack of Nitrogen in the soil?

They just need moving on into larger pots, as Mattbeer87 says it's a lack on nutrients in the compost and potting on is the answer, they'll soon green up again.

Yep move into bigger pots planting slightly deeper
Keep warm, out of drafts....

If there's a lack of anything, it's more likely magnesium. If repotting doesn't sort it, try spraying the foliage with Epsom salts.
