Hi there, I've just put in some raised garden beds. Filled them with layers (lasagne style) with the last 40cm or so of 'organic garden soil'. I planted a whole bunch of veggies, many of which i have grown successfully in pots previously. They all germinated fine, however, since germination, they have all stopped growing and are looking very yellow and sick. I tested the pH of the soil and it was a little high so i added some sulphate. I've fed the plants with powerfeed and seasol. I'd appreciate any advice. I'm worried the soil is just terrible
