I'm having a problem with my 1st try at cloning.
Some of my clones have gotten a yellowing around the edges, with a brown tint. They are 6 days in.
as you can see below, 1/2 of my clones (the Northern Lights) have the sickness on the leaves. I'm using water PH tested everytime, and peat pills.
If anyone could help me identify the problem, I would appreciate it very much.
