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.
Providing leaves at the growing centre of the plant is looking healthy I wouldn't worry about a few outer leaves dying.
