Not new to growing but new to this problem. The branch tips of clones before they get roots are turning white. If I have 6 nodes going all 6 get bleached out. Clone doesn’t die and it takes along time to come back. I know for sure it is not the light happened under both fluorescent and hps. Attaching a few pics not the best but look close and you can see.
