So I transplanted my Kale plants 6 days ago from pot to raised bed and the lower leaves have turned yellow. Could this be transplant shock or something else? A bit more info on what I've done- I transplanted them, watered them in and sprayed a little Kelp for fertiliser. They are in a full sun position in a raised bed filled with clay soil (at the bottom), compost and perlite (the fine one as I bought this as an accident was meant to get medium) I also sprinkled a little bit of my power pellets into the whole bed's soil a couple days before planting into it.
