Allotments 4 All

My tomato seedlings were started off during the first week in March and looking quite healthy. Over the past week or so the leaves have started to go yellow. I feel they probably need a feed of something but I am not sure what to feed them with. I have tomato feed but I am not sure this would be suitable at this stage of their growth.

Which leaves are yellowing Duke?
If it is the seed leaves it's not a real problem, if it is the true leaves then needs attention...

Its the true leaves Saddad they are yellow with dark green veins. I could take a picture and post it but I cant use the main computer right now.

sounds possible irregular tempretures where are the toms

They were on a sunny window sill so I moved them the cooler conservatory.

Yellow leaves with dark green veins is a classic symptom of chlorosis. What compost are you using? I would be inclined to re-pot to some mineral based compost asap.

I used B&Q multipurpose compost. What would be a good mineral compost...trade name?

i think there is the reason if the temp changes to quickly the plant doesnt recover as quick as one would expect

tomatoes need 17 degrees is the optimum temp anything else causes them trouble one way or the other

I would sugest John Innes no 3

Thanks for your help I have been able to post a photo.

I would say that the plant desperately needs feeding. Have you got any chicken pellets or anything similar for a quick fix?

At first glance I would say the same Eristic but he also says;

The sun might have been a bit to strong through the glass.

The following treatment might work; apply a foliar spray* containing Epsom salts at 20g (½oz) per litre of water. and keep the them in good light but not strong sunlight.

Doesn`t look too ill to me-a bit of sun scorch though?
