Which is a good soil medium that is not too hot for seedlings ?

Ive started two grow in an all purpose compost with 40% John innes peat moss .

Seedlings do great but always by week 3 they start to suffer . There plenty of nitrogen in the soil at this point but I think potassium and phosphorus are less at this point and start to yellow and dry out the leaves . I end up feeding early on pk and it's all good

I'm looking a soil that is light and I can start feeding by nutrient guidelines around week 3 or 4 onwards
