seedlings are not looking good at all, yellow bottom leaves, help!

[qwien]

Hi,
we have sown Top44 seeds on 12 February and soon had some lovely little seedlings.
When big enough we transplanted them to turf pots, filled with John Innes No1. We didnt start feeding straight away, since acc. to the pack the compost should have enough nutrients for at least a week.Soon after though, the bottom leaves (not the cotylydons) of 2 of the 4 seedlings started to yellow, then curled up and browned.
Looking at another forum it said to feed with an Epsom salt solution which we used on 1 of them, but there is no difference.
1 of the seedlings looked quite healthy but has begun to yello as well now, but this time it seems the top leaves, not the bottom.
Please see pictures attached
Can anybody identify what is wrong with our little ones please?

Those are waaaay too young for nutrients. Flush with properly ph'd water, and/or start thinking about transplanting into one gallon pots.

Your ph is too high. Between 6.3 and 6.8 ph is 'normal' for peat-based soil grows.

Do not attempt corrective measures unless you know what you are correcting, and why. It's best to ask here before you kill the plants with best intentions and false assumptions.

You might want to read through some of the grow logs and see how other's are raising their young. Then the FAQ section, then the basic growing threads, and perhaps the plant problems section...:thumbsup:

Looks like fert burn. Too little soil there. Are you sure you've had them growing for over a month now? Very slow, if that's the timeframe.
