I am having a small issue recently with the roots of my cuttings. I think it's the hot weather causing it but I mightbe wrong?
I usually root my cuttings in aero prop with 100% rate and then move then into coco. Never had any issues until this summer.
A week later in the coco and the roots are dead and you can pull the plant straight put.
That below is how they look before going into coco
Then they look the same but without roots

What are your thoughts? I was thinking to add liquid oxygen to the feed?
