I have a 5 1/2 week old lemon ak auto with what appears to be the start of a mag deficiency not sure? Maybe excess? really not sure. first noticed at 3 weeks on the larger lower fan leaves. I have only fed twice both feeds within the last 10 days. Cal mag 200ppm my tap water is very soft only 50ppm, and some canna terra at 160 ppm. Medium is canna terra professional which is peat based. Temps have been a bit low around 22 to 24 degrees its cold here in southern Oz. The plant seems happy enough and is growing well I just don't like the look of the striping within the leaf margin. Her sister has no sighns of the symptoms. Ppfd around 400 dli just under 30. The more I look I can see the striping on almost every leaf, the rest of the plant's seem ok. Seeking some advise from the gurus of ganja cultivation
