Yellow Tomato leaves

Hi All

My Tomato plants are growing OK about 3" high although the leaves look a bit yellow, any ideas what could be causing this they are Gardeners Delight and Beefsteak planted in compost from the same bag as last year and I don't recall having any yellowing of the leaves.
I have been bringing them in at night if the temperature is forecast near 10*

Thanks

Dave

 

Saw something on Gardener's world last night and Monty was suggesting that yellowing of tomato seedling leaves or indeed most seedlings simply means that they are ready to potted on or pricked out and potted up.....??

 

Hi Bilbo

I have researched a bit into this and it appears there is a magnesium deficiency so I have purchased some epsom salts from the local garden centre (£5 if you don't mind) and have sprayed the plants lets hope that sorts it out

Yes, it might be, but it would be unusual in young plants. But the spray won't hurt, and you'll probably need some a bit later in the season.

Was probably much cheaper at the garden centre than it would have been if you had bought it at a chemist :thumb:
