Mine are ok, I think! they are nice and green but are still quite small.

The picture looks like a clump of seedlings rather than one plant. If there is more than one they need thinning out and planting about six inches appart.

I would say they are going yellow because your soil condition is acid. Have they been drying out in dry weather?, is your tap water hard in your area?.

I agree with Bulba. In general it is easier to sow lettuce or salad leaves in a seed tray and then transplant on.

thank you i have just been out to sort it i bet you can tell i am a novis
